Goodbye Galaxy

Just a little sketch I did of Billy Blaze, hero of the most amazing DOS game ever: COMMANDER KEEN! This game pretty much defined my childhood. You squish flying spiders on a pogo stick, zap pooping yellow slugs with a trumpet, and collect chocolate bars and blood soda. BEST. GAME. EVAR.

This is my first attempt at digital painting in photoshop, so if anyone has any pointers, that would be appriciated. I like how the helmet turned out though.
