Nice idea, I like how you show the connection between man and animal. It would have been much better if you had taken the picture form the other side - the one where both the kid and the dog are looking at. The text of the book is unimportant, the cover might even look better. This way, you might also have left the desk lamp out of the picture, which - IMO - you should have cropped anyway. 5.
Studio light in the photo...intentional I imagine. Perhaps child is using time between shoots to catch up on his favorite book. In any event, excellent lighting and other technical aspects (i.e. exposure, focus, DOF, detail) well handled. Colors are a little bit muted. A quick boost in saturation could have cured that.
