Classic Sonic Sprite Sheet. How does it look?

[AkumaTh]

Some of the poses look like recolors of the official sprites. Shading seem to fluxuate between certain actions (compare Sonic's hands when standing to Sonic's hands when crouching or running). You use the same hand pose a lot as the same hand is use for his crouching, walking, and Peel Out. Sometimes his feet doesn't have outlines and sometimes it does. The Peel Out doesn't look good (compare how it originally look to your version), Super Sonic's shading looks weird to me and the animation for a few of the poses don't look good.

 

And to me, while it does match the colors, it feels saturated. Compare how the colors look to your sprites with the Avatar you have. Study the original sheets more and see how they animate and try to match up the shading and fix a few things. It would be better looking if you could.
