@jtk It could be. Haven't decided yet. I'm thinking about portraits and self-portraits since I'm taking a class at the Smithsonian about self-portraits in photography.
@DWThomas It could take a long time to accomplish - it's very easy for the idea to become a one-trick pony and you end up with an awful lot of very similar images that don't say anything different. This one works because it's a shadow of a lamp-post. A bit of an ironic twist - something that gives light is defined by its shadow.
