The ball bounce looks great and the tail overlap works very well. I only have a few little notes:
I would speed up the first bounce a tiny bit or not have it bounce as high and to the right. It feels a bit slow compared to the other bounces. I know you want to ramp up, but the up and down on the first one seem slow as if the ball is controlling the up and down.
On x61 the ball moves very fast to the right (the previous bounce didn't go as far to the right and wasn't as fast), so I would tone that down. It's almost like a little pop. And you could take out at least one of the tiny little bounces at the very end. There are so many and they're so fast, that the ball feels as if it's shaking.
