Just tried to do this a bit differently to see if I get the sky tones better. This is done with less contrast so you can see more detail in near the horizon dark tones. The dynamic range of the original is too wide to be pressed in this web-resolution image so there isn't as much tones in the sky as is the original 60MB...
Still I think this one a bit better than the original. What do you think?

I thought I'd try to get the soft part (snow) even softer by applying a noise filter. Also a slight adjustment to levels and added a bit of saturation. Not meant to be a better version of the original - just a different look.
