Love the first foray into this, it turned out quite well. The play of light and shadow stands out most prominent to the point that the eyes are more drawn towards the hair and eyes then anything else letting the periferals take in the rest. I'd be very interested in see the rest if this was a full shoot, if not then I look forward to seeing more of this in the future. I feel a little bad figure studies wasn't my specialty or I'd love to sketch this if for no other reason then how the contrasts play.
Again excellent work.
Very bold of you to do this.
