Well guys I need some help here. Here are my better replays, I want to know how I can improve these. Any comments appreciated

Well, even though the replays I make aren't very good, some advice I can give you is never stop moving (unless it's for a pose) and rarely does holding a piece of Uke at the end look cool.

Well, you asked for criticism... I agree with NoCheerios about the holding a part of Uke at the end. I suggest that right before you go into a pose, just fling your arm up in a tasteful-ish way and release your hand... there goes the body part

Well usually I strayed away from grabbing uke.
