I think I see what you're going for and I like it, but if you could reshoot it it would probably be better. Seeing your settings, I bet it was a really hard place to shoot. I would personally use a much wider lens, move in and down and shoot at maybe f11. The wide angle lens will keep more in focus, plus the f11 helping. I think that while the wide angle would separate the room more, shooting from closer and slighty underneath the mask would give a slightly more extreme look and dramatize the room some.
Kinda like what I did here. The wide angle make slight tilts skew the image a bunch. I tilted it back just enough to keep the trees relatively straight but make the rest of the building look taller.
Hope this makes sense.
