This is a great subject and you have the perfect arial perspective for it. I would suggest checking out the Rule of Thirds in photography, if you have not already done so, it can be very helpful. One thing that photographers often don't realize in the "moment of the shot" is that placing the primary subject of a photo in the very center of a picture can often weaken the overall image. I believe if you were to retake this shot, and place the spire off to the left or right third of the image, while keeping the domes below visible, could make this more powerful. Perhaps also taking it at dusk or with on a day with a beautiful sky and no smog. A photo like this under those circumstances may take much determination to get, but it would be worth it! :) Have a great day!
