There is a bunch of great inspiration out there! Here is most of my terrain collection: Also here are the walls and towers set up in its standard Jungle Fortress formation. Most of my stuff is still WIP, got a few projects ongoing including finishing this jungle fortress (here are some of the WIP pics), plus some more recent temple construction projects. But there are tons of others on this site, to name a few (I will let them post their own pictures, but here are some links for you) @Jorgik 's jungle trees and other projects in his blog, @n810 's entire blog, @NIGHTBRINGER is known for various wood-terrain-projects as well. Also this one was posted recently from terraingenesis, AMAZING terrain table that I continue to draw inspiration from! Also found this link in the Itza Gallery of Fine Arts, I didn't know @spawning of Bob made terrain!
Unfortunately I do not have any Lizardmen inspired terrain as of yet. Hopefully some day. But anyone interested can check out my blog, the link is in my signature.
