There's something very appealing about this photo. Partially, that's the rather unusual, but very good composition, and secondly, that's the subtle tonal range and consistency in tones. Very beautiful, but that's also the catch, I think. The sand stone rock could IMO use a little boost in contrast, to bring out its structures a bit stronger. On the otherhand, the feel of this photo is so genuine and natural, that boosing the contrast would also reduce that effect. I'm a bit torn between the two, which again, also adds to the appeal. Nice controversy..:)
