Looking good! The only thing that catches my eye is the direction change of the stone pavers in the lower-left corridor. It almost looks as if the diagonal pavers from the section in the right end in the air...as if at a balcony or something. That's what it makes my eye do, anyway. I'm not at all sure how to "fix" it, or even if it needs to be fixed. Can't wait to see this finished.
