I think the sky gives a larger context. There is nothing to change about this picture, as far as I'm concerned. That couple was lucky to have you as a photographer, just for this picture alone.
LOVE this picture!! Only thing I'd do differntly is to crop in closer and lose the sky. But then, I've never taken a professional picture in my life. Love your photos!
wow, love it, only thing that kinda bugs me is the color of the sky, but I love the darkness of the background and the pose is just awesome, excellent picture
