Mh, doesnt seem very realistic.
One of the reasons could be that i think the ball would have a backward spin after bouncing off the wall. But in your animation it seems like a forward spinning since it's getting slightly faster in a small angle to the ground.
And there are too many small bounces at the end -these could be realistic for a small rubber ball, but it obvouisly isn't because you have to much squashing.
What you could do is make a rigid body or ncloth simulation just for a reference.
