Hi Greg, there's a very moody and ominous atmosphere about this shot. Probably because of the dark tones, and the low (almost) backlighting.
In the composition, I do like the imaginary diagonal line between the poles, but it's a pitty the top of the nearest pole has been cut off. It makes me wonder if panning up could've created a larger balance in this shot, losing a bit of the sand, but gaining more sky. Anyway, well captured, and a strong image.
