I'd have cropped out the little bit of branch (or whatever it is) in the very top-right corner. Otherwise, I like the way you have a contrast between warm and cold tones, along a strong diagonal.
Gives the feeling of a great NG picture. This gives the feeling of a place that not many have gone and explored. Composition is really good in that the slopping landscape makes your eyes follow down the hill. The misty background almost gives you goosebumps feeling how cold it is.
Really like the subtle colors and angle of this photo. Was it a tough hike to this spot in the cold? Just my opinion, but I would crop (or clone out) the tiny piece of the tree that snuck into the upper right hand corner of the photo. Nice shot.
