well.... I cant really be bothered C&Cing. Ill try

To get started there is alot, I mean ALOT of resizing. You know. to fix shakiness you could use the line tool. just make sure your anims don't come out to stiff

His punch looks like he is slinging his arm over and sorta bear clawing. try to animate it so that he pulls his arm back there's anticipation then a quick foward movement of his arm and folow it through with a step(to give it flow)

His kick kinda looked like his leg was windmilling if you know what i mean. Kicking goes the same for punching. If your having trouble getting your kicks to look realistic.

The start of his energy blast thing was ok but try to ease it a bit more. By this i mean, start off slow and then go faster each frame the slow down again.

I might cc more later... lool. right now im tired
