PersonallY I would prefer to see this image completely in black and white, right now colour is kind of 'leaking' from his head, in addition it looks like the white balance is off int he first place. By converting to black and white, it will draw more attention to the subjects. I like the composition, the juxtaposition between the mother, busily talking on the phone, as her son's main concern is the camera. If I was to be very very picky, I would be saying to have taken it 0.5ms later and had her eyes open a tad bit more.
Your son has beautiful big eyes!
