Is he supposed to be just bouncing or also breathing? Let the hands/arms relax as his body goes up. Otherwise, his upper body looks too rigid. His head, upper body and waist are also too rigid. Perhaps when he goes down, have the head delay a frame before it falls - the same with the hands (not the shoulders though).

ugh. This took longer than expected.

The animation itself is very subtle so I just moved lots of body parts around. I played with delaying things and stuff. I can't say exactly what I did because I did a bit (Or atleast it felt like I did hehe). The animation is about subtle movement and there's only so much you can do with 1-2 pixel offsetting. Anyways, I hope this helps you understand what I mean by breaking the rigidness.
