Hahaha, great idea! I like the story the photo tells. It seems like the flash properly exposed the paper, and underexposed the man. Frontal flash, especially the built in ones tend to do that to shots. Id try retaking this shot, and playing with the lighting a little. (if you dont have any external flashes, go with a cheap worklight or office light reflected off a white board to fill his face, and you will be amazed at the difference)
fun creative shot! the lighting is just off though, maybe try doing some using the natural light from the window casting the light on the subject instead of lighting from behind
The brightness of the paper really offsets the darkness of the man. I'm honestly not sure what to think of it. It does draw my attention to that point, which I feel was your point, but I almost wish I could better understand the expression in his face.
