Hey all, new user here looking for some cc on a sprite I plan on using in an animation to submit later.

Specifically, I'm looking for suggestions on shading. My man here is looking pretty flat in the belly and mouth areas, how would you shade him to give more depth? Also, this is my first time using dithering. Do you think that I am over/under-using the dithering? All this keeping in mind that I'm going to add some wiggle to his tail and bobbing to his head in the animation.

Thanks in advance.
