Thank you all guys,
An update is in the making.
I made a couple of adjustments:
1) smaller, sharper and more choppy wind patches
2) slightly less soft reflections
3) found a glitch in the snow setup and fixed it
4) made the composition more balanced, by going from 600x900 to 600x840, panning slightly more to the left and tilted the camera slightly down.
To do later
1) break up straight shore line
2) perhaps a tad bit more variation in the trees
What I probably won't do is adding whisps of clouds.
I tried that already and it just looks annoying and unbalanced.
With this typical lighting you can't get clouds which look up to par with the rest of the image.
I think this generally looks quite photoreal, but adding clouds messes this up.
Besides that they are hard to reflect in the water in nice quality and on top of that the whole image becomes a "busy" looking mirror.
What I can do in regard to clouds is adding some blown snow or clouds at the upper ridges of the mountains.
So for now clouds in the desolate atmosphere aren't in my plans, unless somebody can convince me that you can achieve photorealistic clouds at sunset.
I don't want to make concessions to the realism this time.
