Sorry for the delay of my reply (Christmas & New Year festivities heh)
Thank you for this edit too, I like this fog effect the low clouds add to the scenery.
Like you said, it gives less of a "mystic" feeling as I would like. But it should be interesting to work this kind of sky on another set-up, more "blizzard-esque".
Thank you everyone for your critics, it was really interesting to see there are really two distincts point of view on this piece
