I will agree with the majority here.
I think your quilt is very, very beautiful. I think you did a wonderful job on the piecing. I also think the quilting is done wonderfully as well.
I am sorry that you feel that it isn't done well or to your liking.
I have started to save images of machine quilting that I like so that I can tell/show my longarmer what I like or need for a quilt.
Don't be too hard on yourself. It is a beautiful quilt!
