The fog is too bright, the ground is flat, and there is very little tile variation. I would strongly suggest using elveswood trees. Other than that, I like it, especially the palace.
The fog is very unnatural. Is there any reason the first shot is littered with doodads where the two last are near empty?
Nice models though. And I kinda like the first shot. Reminds me of a forest I used to live nearby. It's been a while since I've seen a forest with so much underbrush!
