Figuring out a Background

This last Monday evening I threw down a rough sketch for this. I really didn't have any idea what I was drawing. I'm still figuring it out, but here are a few of the stages I've worked on so far. The main idea was to have the character be stone-faced (no, not stoned). The hair started off really curly, then I decided to switch the hair over to something Farrah Fawcett-ish. I think I may need to just redo the head completely as I figure out what I'm doing with the background.
