I'm not at all surprised this made cover.
Solid composition and beautifully balanced by the shadow of the model and the lines of the dunes. I admire the way that the line of the dues contrasted against the sky seems to echo that of a human form. The tones of the model, the sand, and the sky all work well together here, and I admire the way the lines in the sand pull the eye into the frame.
Take a bow, this is damn fine work.

Nicely done!! Continue to have fun!!
