You seem to be putting a lot of obstacles in your own way inadvertently.
Shooting out in the snow where the light is mostly in the upper range with little in the way of shadows or nice distribution of tones - and is cold toned by definition is very difficult. Additionally the very bright background competes with the girl for attention.
RULE 1: the brightest spot in a picture should either be the subject or be part of some design element. You don't want to attract the viewers' eyes from what you want them to look at.

Now I think one can make this a bit better by
1) adding some more lower tones
2) lowering down the brightness and the focus of the backgrounds a bit
3) warming up the tones on the girl.
but you need to get to that later.
Shoot in more controlled situations where the light isn't fighting you.
