A lot to improve on.
I can see you are really starting to understand flash a little better. When I started animating, mine looked a little like yours. I've been at it for 2 years and I can definitely see an improvement. Next time, try to take a little more time on your animations and try to find better sound effects, instead of having the same bouncing sound over and over(maybe some music too). I can see that you are getting better. Just keep it up and still animate. If you need any more feedback or help I would be delighted to help. Keep up the good work.
