It resized to much. The run seemed kind of rushed, but I think the kick was good. You could of made a still at the end so we know it's finished though. Good job otherwise.
Work on resizing and movements. Then try some different easing styles. It wasn't that bad.
If you can, get a tablet and use the brush tool. It's a lot easier and the style is more flexible. Especially when it comes to doing effects. If you have a mouse and no money, stick with line tool. It's easy with the mouse.
