I realized recently that I didn't have any finished robot pictures in my portfolio, and what kind of a science fiction portfolio is missing robots?! I had these sketches of robots with brains in tanks lying around for a while and was trying to think of what to do with them. But once you've got your brains showing, what could be worse than a pack of zombies, armed with a can opener? (Actually, the can opened was a late addition.)
