oksewglad, I like your quilting just fine. I think the slight variation from perfection is proof that a human being did this rather than a robot, and if you hadn't shown the picture of the design you were following, I would have assumed it was intentional. The variegated thread was just the right choice for this quilt, too. If you have two grands with their eyes on it, you may have to make another similar one in order to keep the peace!
