This is a lovely painting, Terry. But I'd change two things.
1) Lose that tree in the foreground. It stops your eye from following the footsteps to the point of interest, the cabin.
2) As Bob Ross used to often stress; "Don't cover up all your darks." You did that with the trees. An old adage that applies in creative writing also applies with art; Less is more.
So I'd start the trees off darker, add some lighter highlights then add the snow v-e-r-y sparingly.
