You've recorded some great light and nice intricate detail there. There's one thing that bothers me about the composition. The partial circle at the bottom right draws my eyes away from the oculus. The problem is, I don't see how you could crop it out without taking something away from the beauty of the architecture you captured. Perhaps stepping back a step or two would "complete" this area, as well as giving continuity to the circle that is cut off at the bottom. Otherwise, the light is fantastic. I really like how it drops off.
Good point. That little corner has always bothered me a little. I suppose my excuse was that I was shooting very wide through a rangefinder without the proper framelines or viewfinder. I took a few, but none seem to measure up to this one in terms of composition/positioning of the oculus.
