Very nice shots Mike, you're off to a good start.
Wedding etc are very difficult to shoot as the pressure of the day really puts a strain on you as the photographer to get all the shots at the right time since generally you can't do things over if you miss anything.
I agree with Dennis' advice on cropping some of these as they look like they will lend themselves better in portrait than landscape mode.
Things to watch are vertical lines in the background (like the tree) which suit the photo better when taken in portrait.
All up though they've turned out very nicely especially for your first wedding shoot.
