Thanks for the comment. I was struggling with the same problem you are describing, as the shot just didnt' "do it" for me that much. I have a vertical one(and it would have worked very nice I agree) but unfortunately the composition on that one is even worse as I cut of some of the rocks on the righthand side. Thanks for the advice Hugo, I truly appreciate it.
A nice shot, and horizontally, well composed. Considering the tight crop in the lower half (the cliffs) I think a little too much emphasis goes out to the sky; panning down might work, although, that would place the horizon in the middle, and that's something you don't really want either. Maybe a vertical / portrait format could solve it... Anyway, a fine photo, nice tones...
