Russ, I do not often disagree with you, but this time I am exactly on the opposite, so I can not resist to say it as it generally does not happen.
I find the composition well done actually. Of course what you say is true and would work perfectly but Josh composition works actually very well for me.
What I like in this composition is that I perceive a clear intention, in the sense that I perceive a conscient choice from Josh.
If I had to lowered the lights, I'll do it in the main room walls, and keep illuminated the other room in the door.

By the way, I'm always amazed why the ruins and abandoned places are so popular in the North American imagery. Is it because of cultural heritage?
In Europe we tend to avoid these; maybe because we are inundated of ruined castles? Do not know the reason but it always caught my attention.
