I like where you are going with this.
Add a big layer mask dose of vibrance, like around +90 and about +20 saturation.
I’d likely go back in with a spot brush and tone the blues spots along the back edge of the stand of trees a bit. The color of the trees outside of the trees you’re standing in for the shot and the bit of yellowish color cast on the snow heightens my sense of here is the way out feeling.
You get this.
Just a thought.
