I agree with everyone. Very pleasing arrangement. I would see if I could get a solid blue to match or coordinate and use it for an additional border, and make it a bit bigger.
I would just stitch in the ditch around the hexes. Then you could just meander the border(s). Then if you still don't like it, donate it!
I also did a small one for practice that I'm not thrilled with, but I'm still going to finish it to practice quilting a OBW if nothing else!
