I actually like minimalistic pictures like this one. However, composition doesn't fully work here. There is a little "dune" at the top just right to the middle. I think this one works well. But the other one, on the left, near the edge, is bugging me. Not sure why, but it doesn't belong there, it breaks the composition. If you had a straight horizon, with just one "dune", it would work better.
Then, coming to the foreground, the nearest patch of grass is too central. I'd move it to a "strong" point, 1/3 or 2/3 of the image horizontally.
But that's just me. As you can see, everyone here has different ideas on how to make a perfect picture. And this is great! As we are all different!
