I agree -- add a bit of applique. Pick a flower, pick a circle -- either make it big or little (I tend to go for splashy) and applique it down. I would scatter them over the quilt in random places so it looks like part of your original design. I would probably use the fusible, windowed applique method to stick it down and then blanket stitch or zigzag around them (since I can't hold a needle long enough to do hand applique).
