This is a great photograph. I like the model's expression and the way it seems as if she is watching you look at her. You can't tell what she thinks about the situation. It forces you to look deeper into the photo. The way the skin tone and background blends works to draw you into the photograph as well. The catch lights along the body and the white of her eyes and clothing leads you around the photo. Was this what you where going for or am I reading too much into the photo?
I was also wondering about the set-up of the photograph. It appears to me you used two lights; 1 camera right at about the height of the model's head, 2 in front of just to the left of the camera set below the camera level. I'm guessing softboxes instead of umbrellas? Did you use a blue or green gel?
I am trying to learn more and take my photography to the next level by studying the photography on this site.
