Since you are seeking opinions. Those feathered stars are and should be the focus of your quilt . All that work and perfection! IMHO the applique takes away from the Stars. I would use the lovely applique you have already done on another quilt that needs a wow. I would love to see your beautiful stars framed with the green you suggest.

No matter what, remember it IS your quilt.
