I like the light in the pic as well and exposure seems pretty good to me. I don't like that the right post is cut off - I think it creates a lack of balance. The curves on the dunes are nice. Also, the focus seems a little soft - perhaps due to conversion to low jpg. I would be interested to see what the shot may have looked like if you moved to the right, and ran the fence down wide angle from right all the way to the left side, but with diminishing perspective for a dramatic look ...either way, wish I was there.
