I'm not sure I'd keep all the teal/green down at the bottom of the panel, but other than that, it's really beautiful and the fan shapes are very prominent. My first thought was to do a solid border with Baptist fans quilted in the border. But then I thought maybe actually piecing fans into the border would look nice & allow you to bring in more of the colors from the panel into the border(s). I would maybe do a row of Grandmother's Fan blocks all the way around the panel (maybe even 2 rows of the fans, off-set). The other option, if you'd like something a bit more modern would be to go with Robert Kaufman's free pattern for Cleopatra's Fan

Or maybe even if you could find a pattern for a Half Dresden Plate (or foundation piece to achieve the right size), that could look really cool. Such a beautiful fabric. It really lends itself to many possibilities.
