This shading on my robot sprite is giving me a headache :/
Here's what I've got so far:


I know there's pillow-shading on the arm, but every other version I make with shading doesn't look right...

Halp plz :S

If it helps, here's an outline:

Well...

TBH, there's pillowshading everywhere. The outline is too jagged. His arm is too up and why is his arms bigger than his legs? Is eyes need more contrast.

Don't dither, it's very hard to do and rarely works out..
If you want to learn more about shading, check the SPRITING DICTIONARY.

Also Dithering a robot would make no sense, as robot's don't have that kind of texture...
