School project - Zombies

Crappy sketch for an expressionism exercise for school. I suck at those kind of things, so I just decided to go for zombies. It's like, expressing the old part about old people and making it even older. And in the end, they turned out zombie (I'll have to paint it later, but I figured it would be a waste if the pencil sketch got lost).
