How about appliqueing smaller leaves in bunches scattered around. I see what I think are plain blocks of the blue. Can you remove some of those filler blocks and get a more random look that way and applique a few bunches of smaller leaves maybe in a plain block? Remove some of your leaves and use for a pillowcase, add smaller - possibly different leaf shape?. It is beautiful - I also love leaves - when I started embroidering one of the first things I made had lots of leaves. You could embroider some leaves also come to think of it.
