I think the main motif of this image is the graphic-like pattern. I don't like the bottom third of the image, it takes away from the main focus. If you crop just above the knob on the square panel at the bottom, the almost zigzag pattern becomes more pronounced and focused, as it alternates between structure, shapes, lines and sky. I don't think the top left dark area works either, but I don't want to cut your image to pieces, just help you improve it if that is what you are looking for. If you imagine the image without the top left dark triangle, I think that will really improve the image and give it cleaner look. You can accomplish this by cropping in post processing, but you should try to do this in the field. The more you do it, the better you will get at it.
