Nice shot Ian!
I can see how a reflector would have helped this shot but I'm guessing it was not entirely set up and you had to snap when you had the chance. I'm experimenting with reflectors at the moment because I'm only now seeing how they can be beneficial. Mind you, I'm cheap like Water and I've been using a reflective shade that you use in your car to keep it cool.... haven't had much luck yet but like Water said it hasn't made the results any worse!
Did you use fill-in flash in this shot?
