The pose is outstanding Ivar and her facial expression is one of slight disinterest which is brilliant..
I'm afraid I'm not with Julian here. I really want the hands in the image Ivar because they partly define the pose but in this case they are just that bit too far removed from the rest of the image in terms of clarity and reality. The rest of the image is so good that it would easily survive if the hands part of the image was removed all together.
Nevertheless It's a great portrait with or without and the B/W is a brilliant choice for this shot.
