i think a lot of your forms are getting lost in all the dark tones. Try brightening them up. also, i wouldn't recommend using straight across dithering on anything from nature. Try some grass and cloud textures. Since he's in an open field it seems, i dont understand why the lightsource is coming from the left. I would assume the light would come from above. Here's a quick edit that illustrates what i just said.
Quick edit? THATS AWESOME!!! I shall return with my sprite better.
Edit: This is gong to take awhile
The colours in the edit JWW provided are definitely better. I think you should use similar colours.
He won't use similar colours... He will take the same color... Do another shading scheme... ¬¬"... But it won't be a half of JWW work...
I will use similar colors. Like this.
Thanks, Link! Update:
What? Now the lightsources are conflicting, along with the left foot being shaped badlly. His sideburns could also do with looking like hair and not thick round flaps.
