The quilt is darling. I would use a soft red with black dots, or stitch in some black dots to the lady bugs. A little black for the bugs would tie it with the sheep. It does need some contrast and outlining the sheep and the quilting of the sky and grass will help you achieve a separation of sky and grass. Choose the quilting patterns wisely for the grass area and a different one for the sky area. Swirls for the sky would look nice and something with vertical lines for the grass area would work. This quilt may not have the fabric you would of picked, but it will be a lovely quilt. Your work is wonderful.
