The map is supposed to be 3 floors of the same building, but the different floors don't fit together. On the second floor there are two big staircases that probably are supposed to be connected to the platform on the ground floor, but in that case there would be a railing in the way.
The artist probably forgot his own architecture, because there is no hint of stairs on the side of the map with the ground floor.
Also usually the upper end of the staircases is highlighted - which would make the platform more sensible - but then the staircases would lead up to nothing which doesn't make sense either.
I don't really know what the gray areas are supposed to be, probably secret areas, but their setup is very random and silly.
Otherwise the museum looks quite nice, but it has a little bit of everything which makes it a strange museum, although that could help to use the map in different situations.
I liked the idea behind the map, but the execution is terrible.
