I begin by complimenting the photographer and the model.
I see a scene and wonder what precedes and follows it. Within the narrative inside which the image fits, how did this woman come to collared, exposed, and nipple-clamped? Does her expression convey just pain or pain mixed with pleasure? And what will happen to her next? We have what we have. And we have a well-crafted image of a beautiful woman, her breasts bared and nipples in pain. The title of the image is "Ouch;" it fits.
Thanks to the photographer and the model for creating beautiful art which fires the imagination.
A lovely model and subject, I think your lighting is excellent, and I really like how the red brown of the natural leather contrasts with the model. A large print of this would need to be on it's own wall to really let the leather stand out. Thank you for sharing.
