Computer generated ball bounce rough animatic

We were told that a good way to understand what you want your character (in this case, a ball) to do; is to have a storyboard/animatic so the essential key frames are understood and can be put into the computer. I used Adobe Flash for this so i can see what i want the ball to move like, and give it a "cute" persona. I feel the ball in this animatic is too squashed, i need to give it mass, so i shall experiment more with the weight of the ball and there needs to be more of sudden drop due to its weight controlling its bounce.
