Children are great subjects for photographs. I think this particular shot would be much stronger (as would be with most child shots) if it was taken from a lower angle. Adults seem to naturally want to point the camera down at children. This seems to accent the fact that they are small. Your image impact could change dramatically if you shoot from the same level as the child, or even below level :) - setzler
It's a very nice photo. I would have preferred to see it at a different angle however, so more of the face is visible. Also, the fact that the crop is halfway through the keys is a little niggling but nothing major.
