It's an artistic retro Animal Crossing living room. This whole room is not bright because of the dark tone ACNH furniture items like Double Sofa, Iron Entrance Mat, Grand Piano, Diy Workbench, Imperial Low Table, Gold Iron-parquet, Flooring Chocolate Hallway Wall etc.  They all go well with retro miscellaneous items. Also, there are many famous Animal Crossing arts like Quaint Painting, Serene Painting, Calm Painting, Basic Painting etc.  Still, the Glittering and Shining Gold HHA Trophy on the table gets our all attention.
