I'm drawn to this image, it's beautiful - great textures and detail. I'm not sure what it is. It would have made a much stronger cover wtih a title included and with a square-crop.
It's the pits when they change the wording during the challenge! A pretty picture with room for the title within the frame. Could be cropped into a square format without losing important detail. Nice colors. The only concern I would have with it is the lack of details within the shadows.
The colors are nice, but there really isn't anything to draw my attention here. Text might be one possibility, or some unusual rock formation. (I don't count the rocks on the right as the red colors invariably draw my eye to that part of the image). I like the subject and I think there are a lot of great shots that could be had of it.
