Meh, not bad
One thing I'd suggest doing is stop using huge thick lines everywhere. Also, have the feet bend from the ankles, not just from the knees. If you want to use lines I would suggest using lines that are colored similarly to the fills near them (though not exactly the same because then they'll disappear) and having them be very very thin. Also, use motion easing, it makes everything look a lot smoother.
It was interesting, however, somewhat enjoyable. I'll keep my eye out for the conclusion.
