I love how far you see in to the distance - gorgeous photo. I think the only thing I would do would be to darken the trees a bit (PS curves) to give it a bit more contrast - but I also like it just as it is.
I would brighten the snow just a little bit and darken the darks - to have more prominent leading lines in the road and more details in the trees. But it's all optional - it is great as it is as well!
A gorgeous snow scene. I don't know what you use for editing. I use Photoshop CC, and I might have gone into the Camera Raw filter there, and used the Highlights slider to get a bit more detail in the snow.
