Resizes a lot in the fall, and you should animate with a line as a floor. Because your fullbody is floating up in the rotation.
Also, there is something wrong with the legs in the second step. The leg should be behind the other leg, not in front.
The rotation looked good.
That's barely a fullbody. It (sorry to be harsh) blows. There's a ton of resizing and its drawn horribly. The movements are awkward, and dare I say wobbly?
