Great perspective and contrast. Seems a bit too black in the sky, and that may have affected your clouds a bit. Still, one of my favorites in the challenge--9 from me!
This image is very well composed and has a great perspective, a beautiful image; BUT I have have problem with the processing. With an image this compositionally strong and so much going for it, it strikes me that far to image management has been done to it.
I like this because its interesting. The tonal range is stark and you've managed to avoid the haloing around the ridges etc. Good control of the hot light on the horizon as well. One of my top 3 picks. Good luck!
