If nothing else, read the want ads (Collabinator) for proven game makers who're looking for some fancy pics :) For a while there, everyone was screaming for BG artists, but that's abated... "My old man said, if you can't find work, you ain't lookin' hard enough." -- Jayne Cobb, Firefly (early 2000's sci-fi by Joss Wheadon)

Hm, maybe try direct marketing - check out the top best games/RPG's, see if they're in need of a graphic artist. This guy's still active, and has produced quite a few hentai games... I know it's not what you were looking for, but somehow, he came to mind.... http://ghoulra.newgrounds.com/

It's cool. I'm actually not really needing to be paid I want to just to work on characters that will eventually make it into a uploaded game.
