The mist in the sky looks good. The brush is nice as well.
The snow is definitely the part that is not working on this one. There is no way that snow escapes all shadows, and with that steep hill on the right it looks like much of it should be in shadow, and with the trees and brush casting shadows as well.
It is not that unusual to see fairly abrupt edges on snow, or drifts that fall down into lower areas. But that soft edge is not reading well.
