#3 is my favorite. The last one has a big potential to be great. I love the color and the background. I dont like the pose though. I NEVER ask the groom to carry the bouquet . I think you need to use longer focal length too when you shoot formal. What did you use during the formal?
I like #2 but some perspective correction would have greatly increased the quality of the photo. The tilt is causing the piece of window to stick out on the right side. I would line up the photo flush with the blue siding and get rid of that piece of window.
