It's worth noting that postcards often have some truly outstanding work on them, albeit usually in a particular style. I disagree about popnfresh's take on the foreground, I think the expanse of earth is a necessary balancing element. The sun overhead is problematic, but well handled it can give a good sense of the desert/heat, and I think it's pretty good, here.
Basically, though, I think this is an image of the interesting (to me, at any rate) clouds below the tops of the mesas. The rest is just context, and as such it's pretty well handled. It might not be genius, but it's appealing.
