Dude.. the girl not looking at the camera (#3) is not acceptable IMO. It is your job to get their attention. Or take a lot of frames and move one head to another frame so everyone is looking at the camera.
Ya there was some grass reflections going on and I shot in sunlight with that one so there was shadow type stuff I was working around. Could have spent more time on the face color balancing I am sure. Thanks for all the comments.
