I like the shot but explaining the approach I would take got a little complicated so I have been audacious enough to do a quick edit which when I see it beside your shots I will possibly no longer like it...
I have burned in the mid ground very slightly with it set to shadows to increase the contrast slightly, toned down the left hand sky and done a small colour adjustment to the foreground snow. May or may not be an improvement but at least illustrates another variation.
