My favorites, personally are #3 and #6. I think #3 was a nice composition, and #6 was a very sweet and playful shot of the bride and groom.
I like the idea and composition of #7, but I think the backlighting distracted from the photo quite a bit. If the horses wouldn't be spooked by a camera flash, I'd suggest using a stronger flash or light source on the bride and groom's faces.
As far as getting the bride, groom, and other photo subjects to be "relaxed", there are a couple of things that have helped me when assisting @ weddings:
1) Try to get to know the bride and groom so that you are all comfortable with each other.
2) Have fun with it. If you're stiff or show that you're worried, that will rub off on the subjects. Try getting them to laugh, smile, and enjoy the moment. When the subjects are enjoying themselves, the joy will show through the photos.
3) Don't try to "force" photos. If you're trying to pose people (especially people like me who hate photos of themselves), it's going to look forced. Most of my good wedding shots have been of the "pop-up" variety -- I'll work the room, catch people laughing/dancing/having a good time, then vanish so I don't intrude on the moment.
I think that, overall, you have some good shots, and my points are not meant to detract from your work.
