Very nice picture and a very happy looking child, Good Idea too... It looks a little canned or perhaps like a studio shot. I gave the photo a higher than average shot based on that. If there had been more detail in the picture to indicate that he reallly was 'letting go' of the bars while riding I would have given 2 more points. Sitll a great idea & picture.
I would have used a white background and worked to remove the red eye by moving the light source a little to make this en even more fun picture than it already is.
