This is gorgeous quilt top! Personally, I'd like to see it LA quilted 1/4 inch in from the feather stitching to highlight that detailing. I might also choose to quilt one or two of the sections in each block with a series of small motifs. I have tied quilts before and wonder how you could best place the ties. Some of the blocks have a fabric division very close to the centre diagonal.
Whatever you choose, I'm sure this quilt will be wonderful. Please post again once it is completed.
