Snow on the countryside: Branching out to the sky, fading from white

Here are some trees stretching out to the sky.
I love the way the snow covered the branches, it's like a white contour around the trees.

In this image I've pushed the local contrast to enhance the "white contour" effect, I've also faded out the saturation in the lower part so that it give more the idea of something stretching out to the sky (and the perspective does the rest :-).
