Nice capture, this is one of those shots I may have preferred see in color. The one distraction for me is the darkness of the rock towards the center of the shot makes it feel somewhat centered even though it is not. If the rock on that edge were lighter and maybe a slight change in the cropping it might help IMHO but still a very cool shot.
This has some amazing elements, but for some reason they don't work together for me. I think it's the composition, but if I managed that capture and the composition was a bit off, I'd submit it too! :P
oh man, if only to capture the lightening framed by the arch, or would that be cliche? I like this in b&w but would be curious to see it in color also...nicely done!
