If it weren't you first quilt .... quilt in the sand dunes and maybe some grassy plants, brick work in the lighthouses or outline echo them, water, and sky using different thread colors for the lighthouse blocks. Floral motif in the floral blocks. and see what you like with the rest. Quilting not too densely but what fits.
If you like to draw you could use the Golden Threads tracing paper to make your designs and repeat them ... or 25% rag vellum, or even Press and Seal.
