I think the one on your gallery that your link points to is my favorite. Great shot. I think the lines in the sand and along the dune do a great job of leading you into the frame and the color contrast between the sand and the sky really make the image for me.

I was fixed on the tree until my attention was called to it by a one of the critiques.
Both are very nice shots.
