I'd remove the green outside border and just leave it off, or, if you need it for size, replace it with, perhaps, the darker blue in the pinwheels. I think the quilt is lovely; the only distraction I see is the light blue pinwheels. They interrupt the flow and movement of the others, I think; their paler color are like gaps in the overall pattern. Just imo, you understand; others may have different reactions. But, if you agree and wanted to do that much work, you could replace those blocks with the darker pinwheel blocks, all of which I like. The narrow blue border and the blue and yellow border I like a lot.
