Ok, i have expreience with Photoshop Elements 4.0, and am wondering what you do making textures for games, and 2D art among other things. All i have experience with right now is mostly Sig images and avatars. Not too much in the renders, but i am starting to use them more often now. Just want an outline as to what this job requires.

well, you're going to have to be able to use what resources you have in an incredibly limited amount of time.
