The scene is presented by night, perhaps that is what makes it look less 'icy'. But still, I agree it needs more snow anyway, gonna work on that !
PS : You could call it 'Nisht-elvish' but also 'High-elvish', and this last name does not belong to WoW at all.

WoW is actually IMO a cartonned summary of decades of fantasy, especially Tolkien's LOTR and Jackson's adaptation. I don't want to look down at what they created, but just remind that they certainly not invented the style.
One decade ago, the popular WOtC's Magic collecting card game already largely represented fantasy worlds with colourful paintings. This is just an example.
See you all !
