this is a very pretty scene and I really like where you're going with this. I must say however that the snow appears more gray than white, and I like the depth of field effect you have going, but think it would be more effective if the focused part of the image wasn't at the very edge of the frame, I wish it was just off the edge so you have blur on either side of it instead of just to the one side.
I thought it was completely out of focus until i saw the branch in the corner. I think it would have worked better if the focus had been on the first fencepost, and the contrast bumped up a touch. Composition is good, it leads my eye quite nicely.
