My preference is to concentrate on the subject - a headshot is about faces. In the first photo there is a lot of negative space (OK as it doesn't draw attention from the model) above the midline and then a lot of "other" in the lower half. The "other" detracts from the model. The hands and black pattern in the second shot have the same detracting effect. In the third, I might crop-up a little tighter - maybe not? I might also move the hair light to bring the top of the subjects head out of the background (instead of the brightness emphasis on the back (as the eye is drawn to brightness). Really great looking model!!
