I think annamaria has a point. The composition does feel a bit crowded. Pulling back a bit wider might have helped.
Not sure how I feel about the processing. Looks like detail extraction from ColorFx Pro or something similar. I like it, but maybe a bit too strong for my taste. A cool find none the less and worth exploring with the lens.
I am going back next week when the weather clears for some more shooting. That's the beauty of doing a place like this; you can go back and fix what you missed the first time around. As to the processing, no ColorEfex used but there was a bit of SEP in a luminosity blend used. These old guys are pretty gnarly all by themselves.
