There's too much stuff in the frame. It seems to be "about" the dome and the cross on top of it, but then there's this big expanse of sort of interesting wall, and then this curved shadow that leads us strongly off to noplace, and so on.
The dome and the cross actually work pretty well for me. Like the red door, it's it's just a thing, but it's a thing fraught with subtext and so on. There's enough symbolism in the cross and the dome for me, a white western guy, to get something from it. Maybe not a lot, but there's something these to hook an emotional reaction to, to evoke some memories and ideas. The sky is pretty good too. I feel like there was a better photograph here emphasizing the cross/dome/sky and eliding much of the other material (of course, now we're starting to wander into the land of overdone cliches, eh?)
