Thanks, Meotter. I actually exposed more for the door, but yes, there is a lot of lost space in there. ...funny how my own eye adds details I remember being there, even when it's clearly not in the photo!
Two little notes. This is actually still the Cathedral I used for two other photos I posted, but I thought it looked like it could be the mythical home of the fabled detective. The Angel would be directly above the door about 50 feet up. There is also no sky; that area between the door and the green is backed by an enormous stone wall.
