A bit stiff, try to hold and relax your joints more.
I know its annoying, but the key to a good replay is smooth movement. To upgrade someones movement he should try to do realistic replays. Put your gravity on -30 and try to do realistic tricks, that helped me alot.
Now a few good points: Your punches and spins already look quite good. I like your replay "funhouse" alot, it shows your strengths.
