Very nice texture, nice tone, I loved the limited color palette that you've used. Did you used a polarizer filter for the sky? A darker blue could go very nice:) Best regars
It's a day for sand dunes... thought that I would bring this one back to the forefront! I like the way the shadow of the ridge leads my eye into the frame, and although I usually like stronger lines in the sand the light you have here is very calming.
My only suggestion would be to crop some of the sky. It's not really eye catching, and although needed for some contrast, I don't beleive that so much of it adds anything to the image.
