These are nice. I like them because the colors are good. What I would do is make one set for balls, and one set for baskets, and then you could make more of each (like a Soccer-ball etc.). And then you would have more and the sets would be more consistent.

Nice! Are these your first icons? They look great other than that you should look at the designs a basketball and baseball and match it with your cursors. Other than that, good work!
