Nicely done. Really captivated the theme your were going for I reckon.
1:30-2:10 is a beautiful melody and I like the way there is just enough "sour" notes to keep the winter feel as opposed to going too melodic.
The recurring staccato string theme is clever.
I couldn't really offer to improve it anymore.
I loved the intro tremolo strings and wanted them to go on longer actually or play a bigger part. Maybe throw some more power into the section I have stated above to make sure that the listener knows its the climax of the track.
You have a very impressive grasp on orchestration.
