Good stuff, man. More specifically, I like the subtle details in hand and foot movements.
One suggestion for the next piece of this: I'd love to see some dramatic camera movement to sell the action.
If you're not already familiar, CS Animate has built-in camera tools:

But, if you're using an older version of flash, you can get a similar effect by taking your entire scene, then dumping it into a symbol and tweening it around.
