This photo was taken during my trip to Namibia in 2016. We had the opportunity to fly over the dunes around Sossusvlei. As you can see, the dunes, combined with the sun, can lead to so interesting lines "in the sand". 
In post, I decided to render the image in black and white, to strengthen the effect of the lines. I also increased the contrasts slightly to bring out the lines even better.
