Nice shots. Some comments:
#1 - There is a lot of negative space to the left. Like Designer said, framed vertically might look nicer. Also, the upper half of the steeple(?) is pretty dark. Maybe try again when it's a little lighter outside, just after sunset?
#2 - Agree. There is too much shrub in the photo. Just a tad less.
#3 - There is something I dislike about the photo, but I can't figure it out. Maybe it needs more detail and less processing? Some of the darks are too dark. There's a fingerprint that's pretty evident that I can't stop looking at. Also, I feel like it should be flipped, with it pointing to the right. Maybe it's personal preference, but I'd rather see the negative space to the right.
