As a landscape I think it's stunning and I quite like the composition, with the road curving away at the end. I would have probably exposed for the snow and cloud highlights, which are clipped.
If you had a raw image and the right software (i.e. Lightroom), you could probably recover a fair bit of detail from the clouds and snow area, which have blown highlights.
There is a slope along the snow:rock and rock:sky interface where you could easily pop a digital graduated neutral density filter to try and recover detail here.
I don't think your black point needs fiddling, however, the shadows on the pines are plenty dark enough as it is.
I think the two things I would do would be to darken the sky and snow areas by 1-2 f-stops, and maybe increase local contrast (clarity) in the top half of the picture, beyond the trees, to overcome the haze a bit.
Composition-wise I would probably add a point of interest in the foreground, being careful not to make it too distracting from the background. Something like a walker resting on his stick looking away from you and towards the landscape might be evocative, though perhaps a bit cliched... Then again you'd need a walker standing by for you in the first place
