Imagine a blank canvas. Now imagine a castle in the background, something to represent power or desire. Now imagine a long walk from the castle to a girl in the front wearing poor-looking clothing, representing not being able to achieve power or desire. Or being held back by something. Then the things that surround the walk, forests and moats, etc., represent things that get into the way. Now. When you look at the whole picture, it sends a message.
