On 1x.com, the original of this photo (shown to the right) attracted three suggestions. Firstly, the suggestion was made to get rid of the white bottom. Being (intended as) an abstract image, it makes more sense to focus on the core element of the picture, i.e. the lines in the sand and the shadows from the dunes. The second suggestion concerned the alignment of the path from the bottom left to the top right to the actual corners of the photo. The third suggestion involved the general improvement of sharpness and contrast.
The repost shown above is the result of taking these suggestions on board. Given the intended abstractness of the image, I would agree that these suggestions have resulted in an improved image.
