Overall I think this is a really nice build. I like the sense of style in the exterior of the building because it maintains a flow throughout the build. The interior however could use some work. The furnishings themselves are alright, but since they all use the same wood-brown color, it doesn't look very good. If you changed their color, and maybe added a few rugs to break up the sea of brown, the inside would look much better.
I think the brown is just fine. I tried to keep it bloko, and it's all wood, just like I want it. Different colours would make it look weird, I mean, it'd be like "oh, so that wall over there is special or something? -nah, it's just more wood."
There is one thing that I could have done, though, which would be adding plate bricks on the floor making it look more like wooden planks.
It also looks much better in-game, trust me.
Of course there is stuff that I would add today, but at the time of this build, didn't.
I really do like making exteriors a lot more than interiors

Thank you for your comment!
