Pretty good. Love the atmosphere.
I think you do a great job with setting the mood of the song as lonely and cold. Now, my only reasoning for not giving it a 10 would be that I would have more "spice" to the song like you add with the reverse cymbal around 2:30 and the celesta at 2:53. That stuff is AWESOME for adding a lot to a winter track, so I think you should visit it earlier than two and a half minutes in. Maybe a vibraphone, grand piano, or even solo strings. Oh, I would also use more bass in the main chords (or maybe my speakers just didn't bring it out very well). Hope that helps!
Check out my remix I just did on Dr. Cossack's Castle from Mega Man 4. It's supposed to give off the same icy feel...at least I hope it does :)
