Color is excellent! The lighting seems a bit harsh, which prevents the viewer from identifying some of the numbers on the balls. This is a small thing, though. Your composition (grouping) was very good.
Hehe, I must laugh, I had this idea myself for this challenge, but I pulled out last minute. Your submission is good, but I would add more DOF, and maybe have lightning from both sides. But I hope this does well! 9
Very nice shot. I think a slightly shallower DoF would be better, as altho the balls are out of focus, they're not enough out of focus to stop me trying to focus on them... if you know what I mean?
