Your quilt is just beautiful. I agree with Karenm36's post above, using motifs would be beautiful, and to me are a bit more fun hand quilting than just straight lines. I think you would like the result. You could do a Motif in the large blocks, and a thin motif in the sashings, or keep the sashing more simple with straight lines 1/4 inch in.
