Background debate

I've done some more work on the hair, and gotten a bit of sketching done. I'm really happy with the hair. Though now I'm starting to question my decision on the background. I'm really determined to start adding more into my backgrounds, but I'm not sure if this will be too busy with the background in it. I also want want to work from the top down on this so I don't smear it later when I come back in to do the background. I need to put some more thought into that. Also I'm really shooting to get this done for a competition deadline, May 1. I think so far I'm on schedule. I don't know though it's hard to tell this early on.
