Sandy, I'll take a shot at a few comments. It may just be that everyone knows you from the Nature forum and is afraid to say anything to hurt your feelings. I know you too, but you asked for feedback and I'm idiot enough to stick my neck out.
Shooting on the beach is not easy, though it's definitely a relaxed setting here. It's difficult lighting to deal with, especially so close to midday with the short shadows telling me it's somewhere close to 2:00pm? You can't do anything about the time and place, it's what you were dealt.
I think if you had utilized some off-camera fill flash to eliminate the shadows on their faces it would have helped quite a bit.
Instead of shooting most everyone straight on I would have them turn in to the bride and groom a little. Shooting straight on makes most people look a little too wide (if you know what I mean).
On the ring shots: the focus of the viewer's attention should be on the rings, not the flowers. With the pillow shot I would have only used the pillow with the rings and left out the flowers. In this instance the rings are competing with the flowers for attention.
I've done some wedding stuff for family and I was a nervous wreck. I made mistakes that you learn not to make again over a period of time. My first was not to shoot them anymore.

That was just me though. You said you enjoyed it, so you're better off than me. You had some ideas of how you wanted to shoot, as evidenced by your selection of shots. Keep at it if you like it.
