Splendid capture! Have you tried flipping it horizontally? I know it would not be location-realistic, but I think it would work compositionally better.
Forgot to say that you bring up another interesting topic, which is changing the scene after the fact. I'm gradually moving in the direction that anything I can do to an image that makes it better is just damn well fine, unless you're trying to capture a landmark and wish it to represent the landmark as closely as possible to how you saw it. But there's the problem.
Sometimes I see sunsets that are so saturated and the sky so blue that it looks fake in real life. So when you get home you need to desaturated them and turn down the contrast. So that brings up the next question: What if you have a very nicely composed image that is under saturated and lower contrast in real life, but when you bring it into Lightroom and make a few small adjustments, the colors and contrast pop and you have a really nice image--the way others "have" seen it, although unlike how you saw it at that time?
The same thing goes for cropping rocks when you can. Should I miss the shot simply because my camera is x aspect ratio instead of y? And if cropping results in a lesser image, what about simply cloning out the offending object while leaving the space?
So I'm beginning to be ok with all of that above, but where I stop, for landscape, is cutting and pasting, for example, a sky/cloud scene into an image because the sky was devoid of anything interesting. But why not? The same argument can be used that I used above. Conversely, I would have no problem cutting and pasting elements into commercial work in order to illuminate the product better--and that's good commercial technique.
But back to the "natural" landscape, if one wants the image to look "natural," as long as it looks natural, why not manipulate away? I mean manipulating images gives the photographer more latitude to express his or her creativity, regardless of whether or not that creativity results in a winner or a loser. Photographers have been doing it since film was invented, cropping, vignetting, letting the image sit in solution longer to pump up the contrast, using Velvia film for those over saturated scenes, light filters, graduated filters, everything.
