I like the displacements on the bottom half of the image, nice work!
Maybe you could try to improve the surfacing a little and make it less "vivid". Don't know exactly how to express what I think of them, sorry.
A nice idea would also the give the snow slightly higher fuzzy zone settings on the slope restrictions (surface layer -> slope restrictions -> fuzzy zone), then apply a little offset on the displacement to give the snow a bit of volume/depth (surface layer -> displacement -> offset --> don't know the scales in your tgd but you might start with an ofset of 0.5 and see the effect).
Another suggestion is to increase the densities of the hazes to create more depth. The background is almost as clear and sharp as the foreground and increasing the densities of the hazes will make the background look more fuzzy/misty, thus creating more sence of depth.
Looking forward to see an update
