I think you should be doing more with the arm that you're not using than just have it penduluming down there. Try flinging it around the head bit in some bigger movements.
I think the foot placement was slightly inconsistant, although it's admittedly hard to tell with the camera movement.
Biggest problem was the balance. He lost it at least twice, possibly three times (I can't be bothered to go back and check again). You gotta keep his centre of gravity over his base, remembering momentum.
Also, the back looked unbelievably jagged. Get a stick with four back joints.
Not too bad though on the whole.
oh o.o you are really a negative guy. ._.
and thanks for negative comment ^^
