That is a gorgeous quilt!
You are very accomplished! I like your leafy design, but I'd add more leaves, just because it's such a large space. I think 4 would be a minimum. Or you could make the leaves bigger and add veins to their centers. Veins don't have to all be identical and waviness is often a plus, so they'd be fairly easy on a dsm. Good luck to you! Lucky giftee!
