>>3421278I don't know what you're going for. If you just wanted the silhouette you should illuminate the wall and put something black around the subject so no light bounces back on the face. Remember this portrait doesn't have to be anonymous.
>>3421832Still you? Light source coming from below has an unsettling effect and is generally not very flattering. I'd put the light a bit forward so the shadow of her cheek goes a bit further on the nose. Use a tripod or stack some books to stabilize your camera. I don't know enough about portraiture to give more tips, but hopefully some studiofag will comment.
Bumping with some (bad) single light portrait from 2011
