I love the design of the charecter. His facial expression is just great.
Be careful with the amount of dither you use, while it is possible to animate with dither, it gets increasigly frustrating the more dither there is and the more dynamic the animations are. I'd love to see more, I really love this sprite.
I think the shading in the face is darker and rougher than the rest, but it looks nice.
