Feedback? Well I guess the only thing I have is don't be scared to quilt it. You already know how to sew and make dolls, and those skills carry over to quilting. If you relax while quilting, you'll probably end up with a much better product then if you let fear get in the way of what you really want to do.
Lovely top by the way. Your use of values really gives the top great movement and you haven't even quilted it yet.
