I really like the drawing, shading and style, but the animation is rather simple, it could be worked a little more. Like his belly, it changes from light to shadow really quick, looks like his muscles are goind inside his guts! XD

Otherwise, really nice done! 6/8

This is great!

C+C? Ok... Put a transparent background, that cyan color it's awful. Maybe adding some frames to make it smoother?

Cool

Smooth, yet jumpy at the same time. I think this would benefit from more subtle movement rather than exaggerated ones.

All fantastic work, very smooth animations.  Would you mind making the backgrounds transparent, however?  We typically only allow stark one-color backgrounds if they serve a specific purpose (and these would look better on a transparent bg anyway)

Amazing drawing! And perfect standing animation.
