Looks good as far as a general ball bounce, a few thing's im noticing. The first bounce goes too far, and wouldn't actually hit the wall, or at that height at least. Then the ball loses it's bounciness on its way back, so you can fix that by changing the original and first bounce, or readjust. A neat thing I like to do to get it right is use dynamics on a ball, and just shoot it with an ini velocity w/ gravity and see how it reacts. I'm a cheater
Better than my first ball animations..
