Now that I've seen this build in person I have some criticism.
Terrain is highly localized; the ones pictured are just part of one small ledge, and the rest of the terrain consists of flat baseplates. All the buildings are also located on these flat baseplates, making it harder to relocate to add terrain, if wanted.
Some buildings don't make sense. Specifically, the dining hall that has a huge exit but isn't attached to any building.
Trees. The low hanging quality of them is okay, but they're not tall enough. Leaves are also compacted rather unrealistically and look bad, though coloration is good.
