Nice Idea here, I like the composition, though there is something a little off about the colouration of those trees they seem really washed out. Also I would like this better if there was a distinct end to the trees - at the moment they seem arbitrarily cut off.
this really is beautiful. sorry to nit-pick about the split horizon, but i really think you'd have a stronger image with about 20% more foreground and 20% less sky. you did good work with the exposure; too bad the clouds are so dull. all the same, i'm sure it looks nice on your wall.
I think a different crop would have worked here... to go along with the rule of thirds... I'm not sure you needed quite so much sky... and would suggest cropping fairly close to the top of the trees. I like the shadow, is there some sort of a color cast here? that may be intentional... and if it is... I like it, gives it a different look.
I LOVE TREES! And I love this; my only "nitpick: Would love to have seen a bit closer crop on the trees, those shadows are great and I would like to have seen them "featured" a bit more.
Utah is an incredible place to photograpy, I like this shot, for some reason it makes me think of a pack of horses trying to get through the snow, the trees being the horses... Anyhow, I like it.
