I like the colours in the sky and even think the person adds to the cold feeling of the shot. My eye is drawn to the post in the right of the shot a lot (wish that wasn't there) but it's a nice submission. Thanks for sharing.
It does look very cold. I like the contrast of the rock shadows and the white (and very cold) snow...not to mention it's a terrific looking tree. Thanks for sharing this one.
You're so lucky to find such an interesting tree with such a serene background. I'd try to edit out that pole to the right though...it takes away from the shot.
