Nice all around exposure. The lighting placed a little differently to give some shadow may give it a bit more depth and interest. Not sure about the pink cast, but seems to work fairly well with the image.
Great model and lighting work. The composition doesn't really work for me...I'm not a fan of cutting off half the face. I think I see where you were going with it, and an "edgy" composition works for this model but I really would prefer to see both eyes at least.
I notice you have chopped off half her head so that we might better enjoy her cleavage. The choice gives dynamism to the composition; but it also makes me a little sad. There is a kind of gritty sensibility to the light and texture - especially in the arm and that enhances the treatment. I do wish the two spots on the neck were cloned out, because that is where my eyes go. Not only do I miss the one lively eye, but I cannot even be compensated properly by the other assets. Despite my long list of quibbles, it is a very strong photo.
