Hagia Sophia is a great architectural beauty and an important monument both for Byzantine and for Ottoman Empires. Once a church, later a mosque, and now a museum at the Turkish Republic, Hagia Sophia has always been the precious of its time.

Converging verticals on the left trees and the right building prevent it from being a 10 for me, but still a superb picture. 9+
I didn't mean converging verticals, I meant wide-angle lens correction (in Photoshop if you use it).
In my opinion: subject - 10, composition - 8, process - 9. Overall - 9.
