1. Here's our base:
2. First we'll be using coloring from the previous tutorial which is here. Well I'll write it for you again so you would be sure what to do.
3. Layer->flatten image
RESULT:
4. New adjustment layer->Gradient map create a black&white gradient PREVIEW
RESULT:
5. Now using black brush erase some black&white elements that you want to be colorfull. Make sure that you're working on the top layer which is gradient map, you just have to click on a white square on the layers menu, here's what I mean: PREVIEW

RESULT:
8. Another texture:
SORRY, but I have no idea who made this one, if you know please let me know.
9. Past it on your icon and set to lighten opacity 100% you can edit it(Edit->Free transform) if you want it to be smaller to cover only sky like I did. Duplicate it, erase some parts do whatever you want to make it look good.
RESULT:
10. You can finish now or add some text like I did. I created a black circle set it to opacity 60% and wrote "angry sky." on it with a white font(WST_Ital 10px)
RESULT:
