looks pretty good in terms of overall composition; the buildings lack windows/ornamentation/signage but could be you're doing that on the event layey if at least part of it is dynamic; the barrenness of the surrounding hills is pretty pronounced, maybe they could use some trees and foliage, it depends if you're going for a "minimalist" aesthetic or not, what else...oh, this probably comes to mine because I just discovered the resource in question but PandaMaru's cliff parts could add a lot of verticality and diversity to your cliffs.
I thought the same thing about the windows when I placed the one, but I felt like I would have to extend the width of some houses to make room for them, and you're absolutely right about the baroness of the cliff parts, I think I wasn't too worried about them because you don't have access to them. But I'll definitely add, at least, some trees! Also, with those cliff parts, I actually already have tiles for making the cliffs more dynamic, I just hadn't really gone that far, being how I challenged myself to make a map quickly! I've seen PandaMaru's Tiles and they're amazing as well though!
