Great job on this one. The first example shows some great timing and spacing. I really like the little pin that comes up in the second example and how the ball bounces against it. only suggesting would be to take a few frames out in the last example when the ball is falling. But great work, love it!

Good, I think when the ball is just arriving you made it way too slow, but it's a very well done excercise, you should post it in the forums, in case you haven't, I didn't really check.
