One suggestion: The upper and lower levels of the church seem to be out of alignment, because the door is in the middle of the bottom half, but the window above it is NOT in the middle of the upper half, especially under the curve of the roof. Either the upper level needs to be extended to the left, or the lower level needs to be trimmed to match the same perspective. Does that make sense?
Did you decide fairly late in the process to widen the left wall near the coffins? I'd guess that's the source of the mismatch.
