I think this is a testament to our personal tastes. Your quilt is not one of your favorites, but I, along with others, really find the colors in your quilt beautiful and satisfying. I am making Bonnie's Celtic Solstice right now and I am not thrilled with my color choices at all. Someone else will think it stunning!
I understand why you wouldn't make another mystery quilt. I always wait to see what they look like before investing the time and fabric into a project, since both of those resources are limited. I also go way too slow to keep up with them!
