Terrific job in a very tough lighting location, Ray. When I see your images, I always wonder what my version would look like. My best educated guess is that mine would have an abundance of overexposure and an equal amount of underexposure as well as more than a pinch of noise and a dash of motion blur.
I really like the composition on this one with the escape route in the back catching my eye and leading me through the room and down the hallway. This shot reeks of old world culture. You have a way of using the available light to your advantage.
