2nd post, third shot, photochop the porta potty out of the shot.

I agree with Todd.

The lighting issues are easier to deal with post than the composition.

Resist the urge to center the subjects in every frame.

Obviously sometimes, especially weddings, the subject should be the primary focus, but then you are better off having a neutral background.

Instead try to frame a shot so the environment becomes a part of the composition. You want to create a "scene"

When shooting subjects dead on suggest they look slightly above and off to the side, you don't want them looking directly into the lens all the time.

It's ok to take the time to pose them, get them to lean into each other, create intimacy.
