Incredible levels of detail! Only thing I would "change/add" is that we can see outside and that there is nothing, only empty space. Maybe a few trees placed near the windows could block the view into the "nothingness". Otherwise it looks absolutely pristine.
Your assets are simply stunning. The level of detail and it still runs well. Please can you do a version without all the baked lighting for the main asset and the accessories. Some prefer to have full control of lighting.
