Photo Shoot

This afternoon I had a practice photo shoot for our friends' wedding next week. I am to be the official photographer (gulp) - it is a relatively casual wedding in the forest. I wanted to have a trial run with the light as the photos will be about 4pm. The light was rather tricky with the dappled light so I used a fill in flash quite a bit. I have no clue about using reflectors or diffusers but maybe I can read up a bit during the week. I am glad I did the trial as it will help a lot on the day. We did a few fun shots that they wanted to try - just as well as some of them weren't that easy. I have added a couple of extras and would appreciate comments. I like extra 1 but is the sunlight on the faces too distracting? Extra 2 - does it matter that the background is blown out a bit or should I crop it out?
