What gorgeous light. Masterful composition, and I particularly like the the hair wrapping around her wrist. Gives it a very subtle sense of serenity, likely the source of her ability to melt into the lens.
This is a beautiful piece of art. I have been visiting it and thinking about it since I saw it mentioned in the 1x thread. Exquisite use of light and form. It does, in a way, make me a bit sad on a personal level. Not only could I most likely never "see" how to shoot something like this, but I also realized (after watching too many episodes of a silly TV show) that the beauty of the model is integral to art like this. A shot like this, no matter how expertly lit or framed, would never see the light of day with someone like me as the model. Very selfish and silly, I know. :-) But it does make me envious, not just of your skill but of her light. She truly is gorgeous and you've done well by her.
This is STUNNING, SUPERB, SUBLIME--beautiful light, compostion, treatment, pose, model, eye contact. Everything is perfect. 10 only because the scale doesn't go higher.
