While it would have been nice if the judge had mentioned the strong points of your quilts as well as the weaknesses, if the only thing that she was critical of was the binding, I'd say you did pretty good.
What did she say about the binding? Was she right? Could her criticism help you do better next time? If so, then try again! Part of entering a show and having your quilts judged is being able to accept the comments and improve your work going forward.
