Hi again!

It looks good on the thumbnail. But on the full size it looks like you have this grey glow around many elements which creates a very strange effect, especially with walls. They look almost foggy, ethereal. You also have a drop shadow effect on them which gives them nice dimension, but the glow seems to clash with it. If the walls indeed are supposed to glow, cause, who knows, maybe it's some kind of magic masonry, they wouldn't be casting a shadow.

I'd remove it, or change it to be as dark as the shadow, then they'd cooperate with your shadows and by contrast would make the walls more legible and give them extra pop. I hope you give it a try.
