I think your quilt is beautiful just as it is. Don't over think this whole quilting process. I can assure you your 30th quilt will look different from your 3rd. You'll grow with each one and each one will be better than the last. In time, your tastes will change too. Mine certainly did. I've gone through many phases and styles, but I love every quilt I ever made.
Hang in there and hang it proudly!
