I admit they don't look very happy lol. Some aren't so bad and others make me scratch my head in confusion. Number 2 is from a movie coming out called 'The Hunger Games' - its a fantastic 3 book series that my 14 yr old read during the holidays. Number 4 reminds me of the ring, in a bulls nose and I can't help but think what a vulnerable position she puts herself in. A robber or predator wouldn't need a weapon - just pull the nose ring and you've got control.
