To make this easier to view I'm splitting the requests up into different posts.
Filled requests for
fangss &
reebeecaa. Just click on your usernames on the cuts below for the tutorials you requested! Feel free to ask any questions! :D

First you'll need this image, cut it out with a mask on the layer (you'll need this later + it's easier to fix mistakes). I prefer to use the pen tool to cut out images but use whatever you like! Once you get your selection go to Select > Modify > Smooth and set it to 2 to round out sharp edges and hit delete to mask out the background. When I get to this stage I like to save the original cut out in the large size somewhere in case I need it again, so save it if you want to, it's not necessary though!
Create a new canvas, I work with 200x200 but you can use whatever size works for you. Fill in the first layer with #a9eb62.
Drag in your image and resize to fit the canvas in the center. It should look like this,

Now for the shadow you're going to need to select the layer mask (Ctrl + left click on the mask to load selection) then create a layer below the image and fill the selection with black. Deselect. Then ctrl + t to bring up the crop thingie (idk what it's called, sorry!) When this comes up you need to hold down alt while clicking on and holding down a corner then drag your mouse. See how it's going backwards (or forwards depending on which corner you clicked) keep doing (holding alt while clicking and moving the squares) that til it resembles a shadow. Then when you get it to where you want it to be, hit enter to exit and save it. Set this layer to soft light at 100%. Blur the edges a bit.
This is what your canvas and layers should be looking like,
Create a new layer below the shadow one and take a grunge brush or a watercolor brush (what I used) to get a texture like this,

I used a darkish green (#3d5c1b) and set it to hard light at 66%.

Your icon should be looking like this,

Now take another watercolor brush (I'm 90% sure it was a watercolor one that I used) and use the color #5fb23b. Set to Soft Light at 38%.

Update on what the layers look like,

Now we move on to adjustment layers.
First off is a gradient map, I'm not sure how else to save this so you can use it so download this psd which has the gradient you need. It's set to Soft Light at 100%.

Next is a Brightness/Contrast layer. Set the contrast to 36.
Create a Color Balance layer and put in +26, +24 and -2. TIP! A few months after making this icon I found that setting color adjustment layers like these to 'Color' makes the colors richer and more natural looking so while this isn't necessary for this particular icon the option is there if you like!
Create a Vibrance layer and set it to +40 and +5.
Current look of canvas and layers,

Now ctrl + shift + alt + e to merge(?) the current view into one layer. This was made before I discovered Smart Sharpen (it's awful, I know. we're not going to talk about it) soo uh I just Sharpened it *cringe* and set the layer to 45%. In short; sharpen how ever you normally do so the image isn't so blurry. \
Like this,

Now if you look closly above you can see how his cape, legs and boots look a bit jagged now? To fix this I think I just did the merge thing again into a new layer; used the blur tool and went along just the edges where I felt they needed smoothing out. I then set the layer to 69%.

Much better!
Create a new layer and take a grungy brush and using this color; #95b835 brush on til it looks something like this,

Then set the layer to Linear Dodge (Add) at 100%

Now take this texture (from this texture pack) and use a gradient map to make it black and white. Now flatten the layers, copy the image and paste it on to your icon canvas. Resize it til it's centered and just the innder circles of the image is visible. Now go back down to your cut out of Loki and again hold ctrl + left click to create a selection. Go back up to the texture layer and hit delete to get a cut out of Loki like this,

Oh, and erase from where the shadow is as well!
Set the layer to screen at 73%. Flatten, save, and you're done!

Fin~

I can never seem to find the caps I use soo you're on your own for this one, sorry!
This is the base layer we're starting off with
I'm pretty sure I did my usual with this, Image > auto contrast, tone and color and adjust them one by one or leave one off entirely. Since I don't have the original I can't say for certain what I did but if you do find it, make it look like it does above.
Copy the base and sharpen it (I think I used Smart Sharpen) and set the layer to 39%.
Create a new layer and ctrl + shift + alt + e and open up Topaz Clean 3 (you can find a download somewhere on here) then just hit the I Feel Lucky! button til her hair is smoothed out to where you like it. Hit ok and then erase everything but her hair.
Should look something like this now

Uh..I have no idea why her face looks brighter in this cap??? lol It should be fine! (I totally know what I'm doing here.)
Create a Hue/Saturation layer and set the saturation to +17. Erase the bottom right corner where her jacket is.
Create a new layer and using this pink #e32791, brush over her jacket. Set to Soft Light.
Create a new layer and using this yellow #f7db15 brush over her hair including the strands on her face. (If you don't have a tablet this may be rather hard to do but zoom is your friend! :P) Set the layer to Soft Light at 41%.
Copy the layer you just made and set it to Multiply at 42%.
Current canvas view

Create a new layer and take this skin color #ffe5e6 and paint over her face like so,

Set to Soft Light at 100%.
Create a new layer and taking a light grey #6d6d6d paint over the shadows like this

Set to Soft Light. Copy the layer and leave the settings as they are.

Create another Color Balance layer and erase the mask from her face and jacket. In Midtones change the settings to, +2, +2, -19.
Current canvas view

Create a Hue/Saturation layer and set the Saturation to +14.
Next layer is a Gradient Map and since I still haven't figured out how to save just the one you need to download this psd for the GM. The bottom right corner where her jacket is, is erased. The layer is set to Soft Light at 22%.
Current canvas view

Take this color #f6e9ea and brush in the upper right hand corner and use Gaussian Blur til it's really faded outwards like this

Set to Screen at 55%.
Final layer is a Selective Color layer. Erase the mask from her jacket. In Reds only change the settings like this +13, +15, -10, -25.
Flatten, save and you're done! :D

Here is the original image. Go to Image then click on Auto Contrast. Then click on Auto Tone and reduce the opacity some and do the same for Auto Color. Try to keep the colors cool looking. I did it myself and I got this result

I put the rest of the psd on top of this new base image to see if it would still work and it did so as long as you get it close to that, you'll be fine!
Create a Brightness/Contrast layer. Set the brightness to 10 and contrast to 23.
Create a Hue/Saturation layer. Set the saturation to +12.

Create a new layer and ctrl + shift + alt + e to merge the current view into one layer. Sharpen it up a bit. I use smart sharpen and my settings that I use for everything are this, Amount: 70% Radius: 0.5px Remove: Gaussian Blur. Now when you've done that hit ok. Change the layer Opacity to 52%. I never leave my layers at full opacity. I make them pretty sharp so I can reduce it easier with the opacity level. Of course if you have a better way, do it! :D
This next section is optional, if you don't like noise in icons you can skip this part!
Create a new layer and do the same merge thing as above then go to Filter > Noise > Add Noise. My settings for the noise filter are always set to this,
Change the layer opacity to 54%. Again I make it fairly noisy to easier reduce it later.

Create a new layer and take this blue #2e3962 and go over this part of the ship here

Set to Soft Light.

So I was going to do a full tutorial until I saw how many layers there are. 37 of them. D: Um..so have the psd! ~here~ I can't find the original image either, I think it's from the latest season with Clara? :\ idk, sorry! Let me know if you have any questions!

Here's the screencap we will be using.
Crop it to whatever size you like work with. Then go to Edit and hit Auto Contrast then Auto Color then Auto Tone.

Create a new layer and fill it with this pink #e42692. Add a layer mask and make a cut out of Dany.

Alternatively, you could just cut out Dany first then create the pink layer underneath the cut out. Whatever works for you!
Create a new layer and take this pink #e5c9d9 and paint over the background mostly on the right side and lightly on the left like so,

Set the layer to Soft Light. Copy this layer.
Create a new layer and take this grey # and paint with a soft brush on the left like so,

Set the layer to Soft Light. Copy this layer.
Current canvas view

Copy this layer and sharpen it to your liking.
Create a Hue/Saturation layer and erase the background so the mask is only covering Dany change the saturation to +32.
Create a Curves layer and in RGB set it to Output 58 and Input 54.

These textures in the next few layers I'm not 100% sure where I got them from. I think the first three are by
deny1984 who posts at
midnight_road. I have 0 ideas about the fourth one.

I can't find the exact cap for this. It's from episode 7 of season 3. I think this coloring should work with that particular scene in the garden. Here's the base that I'm working with in this,

Create a new layer and take this green #213107 and paint over the visible greens in the background avoid the blue flowers or just go over it all then go back and erase from the flowers. (this obviously is much easier when you actually have the full size cap D:)

Set the layer to Linear Dodge (Add).
Create a new layer and go over the background with this dark grey #262626. Set the layer to Soft Light.
Create a new layer and take this blue #336788 and paint over the light blue areas on her dress like so (zoomed in so it's more visible)

Set to Soft Light.

Create a new layer and paste this texture into the canvas Set to Screen at 29%. (I have no idea what that texture is at all. I thought I hd made it but looking at it I honestly can't remember what it is.)
Copy the previous layer and set to Linear Light.

Create a Vibrance layer and set to Color (setting layers to Color really brings out the natural colors of the image and I do this all the time now). Change vibrance to +30 and saturation to +11.
Create a Hue/Saturation layer and set to Color. Erase the mask from everything except for her dress. Set the saturation to +25.

Create a Levels layer and change the settings to this, 0 > 1.08 > 255.
