If you were to break down this picture, You have the sky, ocean, the rock, silouhette, and the birds.
I would look for a fabric that best represents each of these, the silouhette and rock can be solid or slightly mottled and a slightly different shade from each other. The birds can be embroidered or painted on. Blow up the picture and trace out each element and transfer that onto the back of fusible web, make each piece 1/2" bigger all of the way around so it is easier to work with while fusing. Fuse to the back side of your fabrics. Use a piece of a lighter colored fabric as the back and fuse your pieces on. The sky, then the ocean, then the rock, the silouhette last. Then you can blanket stitch, FMQ, whatever calls to you for the quilting.
