I think this is a really cool idea! I love these rooms. I love all the butterfly models especially, and the unique color combinations.
If I were to change anything, it would be two small things: In the lobby, I feel like those wall-mounted lights (I don't remember what they are called, but the ones you craft from iron) would look better if they were white, since the rest of the furniture in the room is mainly white. And secondly, the kimonos in the yellow-and-blue-combo room are kinda throwing me as it doesn't match the rest of the color theme of the room - but I see that kimonos are a staple part of the overall theme so I understand why they are there.
But overall really awesome rooms, my favorite is either the spa.. or the green roomvery pleasing to my eyeballs
I move the kimono around to see if could get it flow better. I didn't know the iron could be customized to white. I'll do that rn.
