I really like this shot, it's quite peaceful, nice texture of the sand on skin too. My only criticism would be that his head is quite block-black right on top, a little more light on there to catch some more detail of the hair would have been good. Very nice shot overall though.
Hmmm, surely a lot of possibilities here: desert and mirage, dream and dreamer, sleeper and snooper ...
A very ambitious shot (and nicer sand than Dupain's)
