nice shot, however there are a couple of elements that would cause me to rework it.
1) halos, being HDR this is a easy fix, even after the merge process.
2) Warmth, even on my monitor which I know to be a bit cool this one burnt a hole in it
dialing up the warmth has its place, possibly doing it selective here will make for a stronger image.
from a composition point of view, the rock works well, but also has the negative effect of 'blocking' the viewer, one becauses its a rock and two cause its a fing big rock and three cause its bright hence the eye stops there rather then heads for what was a nice sky that morning.
hth.
