Love the reflictiveness on the snow, the low mist and especially the sky, just not the little fluffs, they look like dirty marks on the lens top left. Perhaps just a couple of fuller banks of lower cloud, or not at all. Maybe a small amount of verticle displacement on the snow texture to give a small amount of relief on the patches of ground cover, it will also give the impression of collapsed shelves of snow on your forground rock/shadow.
