Nice composition and contrast. The black frame works well with the lines on the ball. I have one of the other B-Ball pictures and wished I'd used a lighter background like yours. Hope yours is doing better than mine.
The composition in this image is strong in this image. Judging from the white halo around the edge of the ball this image looks like it might have been overfocused. I suspect it had poor focus to start with. The low depth of field where the closest part of the basketball is not focused does not work so well with me in this or other images I see it in when it is the main subject of the image.
