I can tell you exactly what is wrong with it. It isn't at my house.
It is true, we are our own worst critics. Sometimes I make a quilt with a picture in my head of how I want it to look. Then when I finish it, it doesn't look like the picture and I am disappointed. But no one else has seen my "picture", they only see the result, which is usually just great. Try not to see your "picture" and see the beautiful quilt you have made.
