This is a very powerful portrait. You've framed it perfectly, and made it look very authentic.
However, the image is very soft -- whilst it's desirable in fashion portraits, I think, taking into consideration the harsh sun of the desert, the wrinkles on the man, this would benefit from spot-on focus, and a more obvious contrast to accentuate on the desert sun, and the wrinkles.
As it is, I'll give it a 6. |
