This photo has really good colors. They are bright, but not overdone.
My favorite part is how the man on back is looking at the pretty young girl in a skirt. No matter where you are in the world, young men look at young women.
A very nicely done image. Good work on the motion capture, the main subject is crisp, and as Senor Hound mentioned, the level of saturation is ideal. My only thought is that the shutter-speed could have been just a bit slower to increase the 'motion blur' but that's minor.
