Wow, well they're all really smooth, ummmm....
As far as CnC goes, i suppose on the second one the reaction to the blue guy's knock down kick where the black guy slides is sort of weak, it just looks like he was tweened or something after he hits the ice and immediatly begins moving. I understand you were going for a slippery floor, but thats not really portrayed until this happens sense they seem to be acting regulary before that. Oh and the part where hes actually sliding, you could try to make it look more realistic by adding kinetic friction, and make the black guy move a lot at first, then just move slightly after that, but make him move farther then he normally would because theyre on ice. Oh and the throw at the end seemed really easy even though the blue guy is picking up a person.
Obviously in animating this stuff hardly matters, but this is what I try to put into my animations to make them look nicer, at least to myself
