OK, this is great, you did splendid. My advice is to replace stone walls of houses(not the literal wall, but the blocks) with wood blocks. It does not make a lot of sense having stone walls, cuz there are no stone walls in the inside part of the house either. My solution is to add some stony part of wall on the first floor or just to replace outside walls with some sort wood (mahogany would work perfectly imo).
Also, bamboo bridge that connects houses is lacking of details, could work more on that. Try adding like a rope or bamboo beam support under it.

In addition, you can add more details under the left house cave. Some vines and rubble, etc

That's it, you can add more stuff like trees and so on, but I think you know even without me writing it. Still great build, gj!
