This is the other shot I almost entered in the Heart Challenge. Unfortunately, I made a last minute entry and realized a little bit too late that neither photo really belonged in the challenge. I do however like this picture very much and feel that it is far superior (why couldn't I have figured this out earlier?) to the one I entered in the Heart challenge.
I'm missing the heart but this picture is pretty nice. love the way your focal length squeezed everything together. LIghting is nice and I'm sure it must have been challenging shooting environment.
Like the composition of this one, all the elements (archs, flags, ceiling) are leading you to the rose window. The light in this rose window is a little strnage IMO, I can't say what it is. Like it.
