some stuff i found useful. this list is still kind of short but i hope it helps somebody :)
i'll see if i can find more tutorials on this stuff sometime. i know heads and hands are really difficult for most artists, and i want to get a variety of approaches in here
stuff that's outdated, full of broken images, or that i haven't taken a good look at. still, it's interesting stuff to browse if you want to learn about old digital art techniques and communities
