Hey Ben,
This is a very cool view, and I like those clouds. I have been mentally cropping this one too (looks like we all have).
I tried the idea of cropping off some of the sky, but I think the power of those clouds get lost. Those clouds really have a nice powerful motion to them sweeping up from the horizon and swirl up to the top.
Now I like how you composed the ground layer, but I do find those white cap rocks in the foreground to be a bit distracting to me. The white really sticks out from the red, and so the eye gets drawn down to the lower left which isn't good as the eye doesn't get to really enjoy the scene. I think the foreground visually over powers the rest of the ground layer and Marlboro Point. Now... if you crop from the bottom to lose the white rock, going to a pano crop and leaving the sky intact, I think you end up with a really powerful image, because then the ground layer with the points and canyons in the background can really be enjoyed.
So that's my crop suggestion.
