Hi, love the image as well !
What struck me immediately was the obviousness of the wires, straight lines perpendicular to the cathedral's. I was already impressed that the image worked with all the clutter, as I never seem to manage to produce a good image in such conditions, but then I saw that the painter had included the wires in his printing as well.
What I like with this picture is that it makes you question the intent of both the photographer, the painter and yours as viewer/photographer. You wrote about the freedom of the painters, yet he chose not to remove the wires from the picture, as did you, and I may not even have taken the shot.
This will make me think twice in the future !
