The light coming thru the screen was the main light for the scene, I filled with a dynalite strobe with about 50 ws out of a 45 inch umbrella from about 15 feet away. The fill was just enough to hold the touch of detail in shadows.
I think what makes this image and most images work is the model's expression, the look in her eyes, the tilt of her head, all the things that a great rapport with the model brings to the table and last but not least is the great skill of the models I am lucky enough to work with.
