Pup kick WIP -- CRITIQUE WANTED

So a little WIP of one of the many parts of my next 'advanced' animation. Decided to take another crack at kicking/moving. Certainly alot better than my last attempt if I do say so myself

Shout out to , watching his many gif animations greatly helped me.

The belly is to scale with the rest of the project, so it's size will not be changed. Also her belly will move and shake in sync with the kicks ^_^

How do you think it came out? What do you like? Dislike? How to improve it?
