I think it looks good

One thing that triggers me is not being able to make rings with curved walls.

I made this after the game decided to not allow me to make fancy shapes with platforms so instead of making something better I thought fine, I'll make a tower. Then it turned into three connected towers. I hate the middle room, but I don't know how to make it better. I have spent a long time figuring out where to put stairs but I'll forget about that and maybe do that later.
I could make the top tower different to the side towers. Then I could invert that curved wall at the bottom of the top tower and the middle area wouldn't look so trash.

Why are there 2 1x1 rooms? I dunno, because there is. My problem is that what I try to do is often not possible in the game due to the game considering everything mildly interesting to be invalid placement. So then I give up on some fancy fantasy tower... and proceed to make this building that looks like a Pokemon. It deals direct unblockable emotional damage to it's owner.
