I am confused by what should be in color. It looks like you tried to get the shorts/shoes/legs in color but there is some color on the bottom of the shirt and on the tree so I am not sure what the intention was. Cute kid!
I'm not sure if it was intentional but the colour popping onto the tree and shirt tails just makes this image look sloppy in my eyes, as does having colour in his legs but not his arms. I would have scored it more highly if it were all colour, or all black and white.
