Looks awesome! I really love the art and models for all the buildings(and all other elven things). It all looks really cool and I find the walls to fit fine, as they are covered in vines/plants and have a nice tannish tint that fits the forest to me. I was wondering how you make the railways between your walls and buildings for the elves, I don't think I see any in the screenshots.
