This is an excellent photo, as your score indicates. With the constraints of available light, and location, you did a heck of a job. Depth of field is fantastic. Color saturation is spot on. The way you aligned the door really makes this pictur work. About the only things I see and they are really minor, is the cloth covered article in the foreground distracts a tiny bit, and the darker shades at the top of the rooms tends to push the eye down, while the doors pull the eye up, which causes a little tension in the picture. Again this is a very minor point and given the shooting location and available light, there is little that could be done and what was done worked very well.
This is a crazy photo. Each room that's visible shares a common object although not necessarily the same object, which for some strange reason I find fascinating.
Many things to look at and hold the eye. No one subject except maybe the path thru the rooms.
Nice colors too. Very nice. I'm bumping it up a notch to 9.
