If your dissapointed that this isn't an animation, have no fear. I'm working on a fairly long, fully animated cartoon. I'm using the cel shaded look you see in the still in this cartoon. This was just an improv idea I thought was funny and animated.

EDIT: actually, I'd like to ask, whats everyone's thoughts on the cel-shading? I want tips so as I can improve upon it.
