Granted the animation is good and all, but it isn't a good idea to submit tests under judgement. Tests, walk cycles, etc usually gets a really low score if not blamed. If you want to put tests on here, there is something called the "Dumping Grounds". It's the button next to your message button where anyone can post tests at. And with it, you can show off anything to your friends, family, and random users on here. So please do that instead.

I'm not sure if you've added too many different frames or that you hold the same frame for too long.
I'm guessing you wanted this to be as good as possible- if so it's admirable but sometimes less is more.
What's happening when the ball reaches the highest point? It looks more like it bounces off of something rather than starting to fall.
Also, because this animation starts right before the ball hits the ground it looks weird. I'm guessing it supposed to look like it bounces off of it.
