Ah, that's good. Lots of times people focus more on the exterior than the interior.
I'm glad that you plan on adding them since they can make a build look more lively.

By the way, I like the variety you put in your buildings, but I think you should tone
down the complexity in places. If you add too much detail, it can be hard for
people to look at buildings or even discern what they are. In my personal opinion,
it can look as good, if not better, to leave some flat spaces along with detailed
portions, especially if you detail specific focus points more than the rest of the
build.
