Those textures and shapes that weave and undulate in the soil/sand are mesmerizing to look at. B&W was a good choice to showcase those patterns in the ground. As a good shot it needs just a little more...'something' to push it into the spectacular category. One thing that I see that can help boast a bit more visual interest is to tilt and crop the composition. There is a 'main' path of rivulets that if you tilt it to the left it could run at a diagonal across the frame. Those dark rivulets ad the bottom are just going straight up but if you tilt it say 35 degrees to the left then some of those nice dark rivulets will appear to pour forth from the bottom right corner. The top area where there it is lighter would also tilt and either be in or pointed towards the top left corner. With that tilt and crop those rivulets then travel from dark to light at a diagonal across the frame.
