I like the concept, and it definately looks as though light source is single, coming from the game boy. A closer in crop, maybe at a slightly more dramatic angle would have scored higher. It's good that the hands show up, but a little dodging here to improve the brightness on the hands would be nice just to show its being helped. Background might have been better plain, instead of the couch.
this is where the image could have increased score most. image isn't really sharp enough, and focus doesn't seem that great. also, there is a fair bit of noise, especially on the gameboy itself. DOF is important for this shot, and needed to capture both sharpness in gameboy and the face.
i like the amount of light on the face. A little more sharpening as long as you keep out halos would be good. Also crop could be changed. Noise could also be reduced with the use of something like noiseninja/neeatimage.
Great idea, but the execution wasn't quite right. It's a very real image of kids nowadays, playing gameboy till late night. Had the technicals of the shot been improved, i'm sure it would have fared much better.
