while this is not a bad animation by any means, its really stiff and doesn't offer much. If you're going for slap stick/physical comedy you need less in between frames and more emphasis on the beginning and ending of an action. Maybe some stretching or smear techniques to add exaggeration to the movements. I know it can be done in 3D animation its just a matter of finding out the methods that work best for you and your animations.
Hope this helps you out in future projects
