This is very pretty! Your idea for quilting will also be very pretty on this quilt. The other one you did is very nice!
Just a thought: Have you ever considered purchasing a stencil for blocks, then marking the blocks, and quilting that? It's an easy way to get a lovely pattern, and makes it very easy to follow the lines for the quilting. Many longarmers do this for the quilting motifs, but it can be just as easily done on a regular machine.
Good luck - and would love to see what you choose!
