In most of the quilts that I really like, there is one 'pa-dow' fabric. The one that says 'look at me!' When you find that one fabric that you absolutely love, work off that and coordinate your other fabrics to that.
It would be nice if you appreciate your own work. That may come with time. There are some quilts that I've made that I'm not quite fond of. But then again, once given, I usually don't lay my eyes on them much. If the recipient enjoys your quilts, that's good too!
