Choppy.Needs double framing to make your animation looks good.
CORRECTED CNC: It's not that choppy. He just needs to work on simple movements first, for example: try looking for tutorials of basic attack recoils/movements. I noticed some resize in the first one, with that spin handstand kick. Try making guidelines to prevent this issue. 2ND one: I loved that blood. but the general stick movement was pretty wobbly. I also didn't know where the top half of his body went. try to make your movements dynamic. Like bend his back further to show that he used a lot of force. Also, the reaction of the black guy wasn't really understandable, it would actually cut him in half, vertically instead of horizontally. other than that, I loved the animations.
Also note: He doesn't NEED doubleframe, it's just simple preference.
