This looks over sharpened and the skin tones don't look right (over saturated?) I'm not sure how to help with the skin tones though as I'm still trying to figure that out for myself...

Nice snapshot - great expressions, but the other skater in the background is rally distracting and there's more blur in the forward boy's hands than I like to see.
:-) Good shot here, shows the emotion in the kids faces. The movement is good. Also like the guy in the background who looks as if he's about to fall over!
