I yhinkk you got enough opinions on theis matter so I just want to say you have made a teriffic quilt and good luck at the show.
If it is a local show and you are dilivering it personally for entering, the people there will help to catagorize it for you.
Also if judges think you missed the mark on were it should go they sometimes will place it in the proper catagory for more fair judging.
Good luck and let us know how you did. It's worth being in the show just to view even if it doesn't take a ribbon!
peace
