With glances at each other and a few badly-covered up "throat clearings", Nancy's husband and his friends all unanimously declared her new dye job as top notch, and unfailingly beautiful.
What I like best in your image is that you have captured an "attitude" beautifully. Or sure, you started with a lovely model, and the composition is terrific, and the focus is spot on, the lighting is dynamite, the colors are arresting, ... so you got off to a good start, and I could go on if I wanted you to become full of yourself. But with all that, you delivered an emotional payload with the photo which I like very much. Congratulations.
The fact you can't see her eyes - not even a hint, really adds to the "coldness" of this. And yet her skintones and hair in the foreground give off a warmth - very interesting contradiction created.
