Which design aspect are you better or more comfortable with?

I don't build that often, but when I do, the exterior of a building tends to be fairly uniform. Individual rooms can be more distinct so I have more experience with interiors. I also try not to use too many objects, so I cut back a bit on my exteriors/landscaping. I make the buildings as big as I want and inside I put as many objects as I want, but outside I try to be fairly reasonable.


Nothing is new, but some interiors/exteriors for reference.
