If you're a photographer, and plan to do only a couple of small weddings a season, do one just like this.
What I mean is, shoot for two of the nicest people you could meet. Make sure they're as smitten with one another as these two are. And while you're at it, have the whole thing happen outdoors.
You know, just a few minor requests. ;)
Oh, and don't forget about the cute kid-o's.
