This is a really good picture. I was letting the challenge scroll through CoolIris and saw this one pop up. It is very impressive in that mode and scales up very nicely.
I like this shot soo much more than the ones of this model from the glamor challenge (not to say that those were bad). I just love the energy in this - the model's hair is perfect for this kind of shot. I just wish that that one strand of hair was not in front of her eye!!! I'm sure you'll get a ton of comments about that - I feel your pain. Wonderful shot, though! Wonderful processing on the skin - very milky feel to it.
