Usually a lens flare like this is a problem in a photo, but in this case it's an asset. I like the way you positioned it against the roof support as though it's peeking around the corner on its way somewhere. The flowers are a good touch too, and the silhouetted buildings are lovely and peaceful. By the way I noticed that you centered the background spire in the foreground arch - nice touch.
A most perfect spot for that sun to come thru at !! I love how the arch is in the front and then below and back, there is another arch, and then all the ones by the windows...so it goes from large to smaller to smallest..very nice!
