ahhh ;w; i dont really like using psds by other people so i usually do my own from scratch for diff edits which just consists of simple levels/vibrance/colouring ;; i cant do anything else other than that ;__; and they usually come out pretty crappy
Actually I stopped relying on psds too, at least for gifs! I'm following itsphotoshop, they have a lot of good tutorials that work without psds :3
I recently have a thing for rather pale looking edits, that's pretty easy to make when you simply make the picture lighter and lower some of the saturation. For gifs I'm usually making them lighter and adding medium contrast then or the other way around. Sometimes I'm adding an action for sharpening and blurring, but I guess that's possible doing yourself, too, without using it from someone else.
