It's lovely! I have come to realize that just the overall medium stipple or meander makes a quilt look the coziest. With all the fancy quilting you could do, the stipple gives it great texture and makes it look "quilty". If it shrinks in the wash, fancy quilting will be obscured, anyway. So why not just a stipple?
As Iceblossom pointed out, if you meander you can put in some simple stars here and there. That would be cute and echo the quilt design.
It doesn't always have to be complicated to look good.
