I like these a lot, and for having to work around people I think you did a great job. #3 and #4 feel like they have a little bit of lean to them. In #3 the bottom of the door frame is obviously level with the edge of the picture, so I don't know if you're not square with the door or if the building leans. I end up with photos like that all the time, and I really need to figure out what I'm doing wrong (personally I have a feeling I'm not lined up with my subject right since I take pictures of new buildings, and I'm pretty sure those don't lean

).
I think my favorite is #3. The aged/dirty stone almost gives a natural vignette to the door which really draws your focus to it, but then the sky is also drawing your eye to the cross at the top. Very nicely done.
