Knight Diner - Mary Sue

I actually got the colors finished up and thought I'd post my results.  I'm contemplating on putting a background in and I think one would make the character pop a lot, but I haven't quite come to a good conclusion on what I'd put back there.  Any ideas would be cool and appreciated.  I thought about maybe putting a small diner scene in or maybe putting her outside of the building delivering a sunday to someone.  I'm not sure yet, but I like how this turned out and had fun working on it.
