Very simply beautiful. As are your other pictures. You wouldn't happen to do any full cosplay would you? Or was this just a spur of the moment "put the mask on" kind of thing. haha
It's a very appropriate use of black and white. I suggest that you try something in sepia. But other wise really quite good. It could have been better if you did dent show off anything but it is covered by the rest of the body. And you could improve by moving your head to face the audience. Yes you could improve but it's a great photo!
