Not sure about the colors: it looks partly unsaturated, which leaves the kid in rather bland colors. Composition is good, but I think I would have cropped off a little bit more off the top.
I like this picture quite a lot, but am not fond of the selective blue toning. It makes the child look a bit.... Smurfy. All over black and white, or perhaps a mild sepia toning, would have done wonders, I think, especially considering the tone set by the title. The composition itself is great, and the focus seems nice and crisp.
There's a serious cyan colour cast to this image which, unfortunately, makes everything in the picture seem syan-coloured, including the cyclist's hands.
