I loveeeeeeeeeee your fabric and your blocks. I don't know if it's my picture or not, but I don't see any of the brown/wine color in the print fabrics so to me it looks out of place. I think I would switch it out for the palest lavender in the larger leaf print. I also agree with irishrose that sashing would lose the patterns AND about trying it with matching the colors in the diamonds to see how that looks.
