Nice animations. It's good to have you here. If I may criticise broadly rather than going in too deep for lack of time, I'd do more with the knee joint than you are, and probably leave it bent longer whenever a foot is coming forwards - you're coming close to scuffing your feet. Also, watch the physics in the second and last ones. You're going down too early, losing some horizontal momentum. But like everyone's said, good work, well done.
