Not all silhouettes are straight portraits. Some show the inner character of their subjects. Here are a few that I like to refer to as my "ex-girlfriends". I'm not naming any names, but they know who they are...
This first one is called the "Backstabber."
This next one is called the "Bloodsucker".
This one is called "Clingy".
And this last one is called the "Web of lies."
All of these (and more) are available at my Etsy site: http://www.etsy.com/shop/BarkingMadArts
