Wow… just wow… I absolutely can’t wait until it’s finished! The build looks very nice so far! Let me know when the build is finished. 
Looks super clean! One little thing that catches my eye are the trees; they don’t have the same feel as the rest of the build I suppose. Other than that, your build looks very nice! Would love to see more of it 
It looks great! I don’t know if this is the route you’re trying to take but maybe try making the lower windows slightly transparent to let a little light in. Also are you using future lighting?
Yep using future lighting the windows are full black since its just dead space behind it
wow looks really good the plants add a lot maybe some vines hanging down from the top parts or something and some more smaller rocks around to. also did you make all the models yourself or in studio
a big statue in the middle or maybe some models poking over the edge of the wall could be cool
1 suggestion I have is the lighting it seems to be the default lighting so maybe making some more realistic lighting would help
anyways looks great can’t wait to see it finished!
Yes most models are meshes the plants are from a nature pack
