The light source seems to come from everywhere on the Treecko PA. And theres no need to dither THAT much. It makes him look... fuzzy. 0-o The feet and arm shading could be left the same, since its such a small area, so itll flow smoothly. I'd say use a little less on the head, and for the tail, only dither it one one side of the shaded area, not all around it.
The stick should also be a tiny bit thicker.
Overall it looks pretty nice, keep it up~
