Weird and haunting...SO much potential in this. But with some dodging you could have brought out the details on his body. and made him less "insignificant" in his own shadows...if you know what I mean. Maybe a tighter crop from the top and then some lightening of his body...? I think I would even have preferred a colour version so that the Contrast function cold have been used to its maximum advantage.
What a great pose the model has! Actually, the more I look, the less I can tell if this is a statue or a real person. Hmmm. I like the birds in the background and think this is an overall nice shot. It might be nice with a bit more contrast or lighting up of the shadows though.
