It's a contemporary variation of a traditional quilt pattern! Which is my way of saying that I agree with what everyone else has said: It's a beautiful quilt in its own right.
You're understandably disappointed because it didn't turn out as you had anticipated. But I'll bet that if you were to put it away for a week and then look at it again with fresher eyes, you'd be pleased and proud!
A dear friend taught me the basics of quilting. While learning to use a rotary cutter and sew a scant 1/4" seam were important, the best thing I learned from her was that our quilts are always better than we think they are. She encouraged me always to set aside a troubled quilt and re-examine it a few days/weeks/months later. It's amazing how much better it looks once I have some distance!!
