I love it. I would echo quilt the fabric dragonflies & then in the larger open areas I'd do a dragonfly in various positions of flight with swirl lines between them representing flight. You could also have some sitting on a flower.
To help with stitching ideas there is a series by Mary M. Covey called Follow-the-line Quilting Designs which includes full size patterns for blocks & borders. I have 3 vols. don't know if there's more, but they cover a wide variety of subjects.
