I mean... I can see a few details.
1. The roof for the building at the bottom left just feels very wrong
2. The placement of the right house that connects to the fountain is also very off
3. Those white things at the bottom also looks very off... (try to avoid 3 wide roads (or any other odd number) unless if you can easily get around it)
4. Personally, I would try to avoid having the building of my starting town too symmetrical, but that is just my opinion
5. The building are pretty cramped together
