I'm aware that these are shot at a bad angle, but because of each room's setup, it was the only I could get all of the portraits, photographs, and sculptures in each picture. Probably should have cluttered them more. The zoom when pressing tab is incredibly sensitive.
I may have to go back and delete the ceiling lights, move the museum pieces closer together, and add the World Adventures tomb lighting. This is if better screenshots of each immortal's museum room is necessary.
