Nice. Festive. I think this would benefit from a little more light on the closest pinwheel. I like the contrasting texture of the background. The light on the reflective surfaces seems to provide enough motion without actually spinning the subjects, but the overly birhgt whites seem to throw the composition out of balance.
Litle more colorsaturation and maybe better lightning without getting to much reflection from the main subject. The color-reflection on the background is fine though maybe it would have been better to use some white cartoon or sheet. Also the green flair left/bottom corner seems litle strange.
