Also watch out for the elbow clipping into the chair at frame 121-122

Joshua Eton:

I feel as if the animation could add or use proper tuning and principles. You should also add better concepts and designs to give out a lively feel.

Moses Justin Ginaba:

Nice

Richard Clark:

Lacks fundamentals. Staging could be better. I would recommend going back to the bouncing ball exercise before jumping into any performance animation.
