Pretty good...
Do you use tweens for his movements? If yo0u do or don't, even, beef up the Frames Per Second to around 24. The original is 12 so it'll be 2x smoother! Just make sure to make smaller changes in his body every frame when he moves. Otherwise, this was actually good! I expected it to be bad, but it was cool. If you can encorporate a good story, this will be a good one. Good Luck!
