Something about the top right of the picture is a little disturbing, the brightness of it doesn't quite work. With this particular photo, I would have also asked the model to look down a little bit (or moved the camera higher), in order to not photograph staight into his nostril.
I like the slightly glazed expression, the colours and his expression, though! Have you tried this one in black and white?
But I LIKE photoing up his nose; it's FUN. I think some photoshopfiddling is probably in order re. that top right corner, yes. And I do have a shot that isn't nostril-orientated which needs a spot of tidying up before I post it. Black and white would be good though. Watch -----> <----- this space.
