Your quilt top is totally adorable, and you are to be commended for doing such a great job on your first quilt! My first quilt never even got finished...I agree with everyone else on the quilting suggestions. I would outline quilt around all the applique pieces (very close to them). On the owl's belly, you will definitely need some quilting. I would do half circles (like clamshells) across the belly, to repeat the applique'd feathers which are there. I once quilted a child's quilt with owls in each block, and that's exactly what I did. It looked great.
