I like the tension between the graphic and the subject of the portrait - but it only works because of the nature of the graphic. If it was something other than "explosive", it just wouldn't fly.
To me it seems that you are better in photographing young ladies with clothes on. This pictures and the one before are the best of the lot. This last one I like the best. There is a very relaxed mood about it. Your model must have felt very comfortable with the situation.
