I absolutely love the leaves and the colors you have used for them! I think your rearrangement that you posted fixes the organized look of the rows of leaves. All I think it needs is a bit of randomness to it. What about putting in a solid blue block a few places in the quilt instead of the leave block, maybe just 4 to 8 places, to give it a bit of a random feel? That would be easy to try quickly to see if you like it. If it works you have some extra blocks you could use on the back, or make a matching pillow!
