to sum it up quickly, doesn't matter about the lighting, doesn't matter about the colors.

as long as you find an appropriate foreground, bring out the mood appropriately, you don't need to have colorful sunsets or beautiful sun rays in the sky. a moody image works just as well as a colorful pretty shot when it comes to photographic merit, in my book.

in short, there is no foreground anchor element here for this shot. so what we see , is a block of land, a sky, some sand. nothing very emotion-invoking here, to add on to that, it does not have much aesthetic value.. and therefore, it fails in that aspect.
