I don't think your nephew is going to critique your quilt. They are very happy looking quilts.
I use to be a perfectionist until my eyes started bothering me a lot. Now I only unrip a seam when it is absolutely necessary because the strain of trying to unstitching hurts my eyes. I find that I enjoy quilting a lot more because I've become more relaxed about my work. I hope that you will be able to do the same.
Another thing to consider...you want one of the quilts to be a little different so that they can tell who's quilt belongs to who.
