It’s a good build indeed, but some things which could be improved are listed below:
On the roof, it looks too flat, you should try and mess around with unions to make a few holes on the roof so you can add some glass windows.
The door is looking really big, perhaps you could scale it down a little bit, and if that’s how you want it, you should make it a double door with glass on them.
I also feel like the windows are just randomly placed on the outside, I feel like there should be a pattern for where they’re placed.
Apart from that, you have a very nice build and I can’t wait for further updates.
