Talk about dedication, I spent most of my day at the pc drawing! Whoohoo.
Concept work is fun but kinda hard aswell if you don't know where you're going.
A lot of playing around and stumbling on things you might or might now like.
Tomorrow is reserved for fun drawing stuff! Now off to watch one last episode of Boardwalk Empire, fantastic show. Highly recommended!
