It's a fantastic and in a way humble (and way too FUNNY) idea for exposing nudity of an everyday person. Killed by the lighting as far as the voting points go... But that's one great feature of DPC: it gives clues to execute your next brilliant idea in a more appealing way in terms of photographic techniques.
A touch of softer lighting might have been more flattering, or perhaps a robe. best of luck!
Was it really necessary to add that "or perhaps a robe" comment? Perhaps you need to realize that he is a human being like you. I agree on the lighting, though.
I am giving you a 5 for this, but need to point out that it is NOT because your model isn't a stunning 18 year old.
The 5 is for a so-so photo with harsh shadows from the flash and a number of artistic/compositional issues that I don't care for in this shot.
Puts me in mind of those naked house cleaners who charge a fortune to clean your house in the nude, lol. Amusing but could do with a bit more work; that dark shadow around him suggests you've used too harsh a light (on camera flash?), plus the crop is very tight. Next time, try a more diffused light or even experiment with more creative lighting. Don't be afraid to try out different crops and angles too.
