I think you have a lens dust issue going on here. It's better seen in the first photo. The buildings and churches are interesting but I am loosing the true focal point in these. There is a lot going on in them.
1: the steeple gets minimized by the building nest to it.
2: the alleyway seems to have a broad look, and no real focal point to it. To me, it's just windows on a building and other generic elements that includes a ford ranger.
and 3: is the best IMO but the power lines take away from the "awe". A little more in camera crop should fix this.
Kudos's to walking around taking photos, but check out that dusty sensor.
