hahaha lets start this one first 
Regarding basing them I want to keep some coherence with my forces of nature so I think I will stick with forest base with some snow, but I struggle to find what decorating stuff using. I dont like grown trees because it looks weird during the game, as if the elves carry their trees with them.
A couple of pics about my current basing (I still feel they are too empty so wondering what else add to them but this time in autum color scheme):
Not the best ones (I’ll add more in the weekend).
Also as the base colour of the bases will be green, I’m wondering if I should add some extra green to the elves clothes; or maybe the skin as @MistakeNot suggested. Any thoughs about it?
If you have some experience with winter color scheme, any advice would be welcome, it’s pretty new to me and hard to see how it fits.
