Lol I can't believe you were lazy enough not to upload 3 mb videos.
The first one is a bit slow when the guy that gets hit gets up, and the other guy is just doing a cannonball on the ground after he jumps. The attack looked cool.
The guy walking backwards looked wierd, it looked like you reversed someone walking forwards.
On the second one, I swear I saw a jump that looked just like that in other videos, did you use a default animation or something? If not, then it looked good. But when he grabs he gets too relaxy.
The landing looked a bit wierd.
