Congrats on your first wedding!

I think you did great. The first and fourth pictures are my favorite. Some thoughts...
Keep an eye out for distracting elements in your pictures, like the roof of the gazebo in No. 5 and No. 6. You can crop that out pretty easily.
Rule of Thirds! I know it's easy to forget when in you're in the middle of the action, but it can really help keep you from just shooting the "easy shots" that are not visually stimulating.
Like someone above said, another way to mix things up is to shoot from above or below or from a creative angle. Don't be afraid to crawl on the floor or break out a folding chair for a shot.
Weddings tend to look very similar to one another, and thus you have to work extra hard to make YOUR weddings stand out from the rest. So when you're faced with something weird and different, say, the FOB who wouldn't take his sunglasses off -- take advantage of that. After the ceremony, encourege him to make a goofy James Bond face or get a cool picture of him looking down at his daughter through the reflection in his glasses.
I want to see more real emotion and small, unposed things that would have otherwise gone unnoticed had you and your camera not been there.
When you're shooting in bright sun, try underexposing the background and using fill flash to get rid of the harsh shadows.

I think there's a recent thread about that here on the Shooting Tips & Techniques forum.
I hope this helps.
