Watson,
when I have a top that I don't like, I usually end up cutting it up and using it in an improvisational quilt--I've had some cool results doing that.
That said, I think your quilt is interesting and your color choices are quite nice. Can you be more specific about what it is you don't like?
Is it because the main motif is centered down the middle of the quilt or is there something about the colors that is not your cup of tea?
If it's the composition, then there may be some quick fix you could do like putting a wider border on one side than the other in order to increase the "edginess" of the quilt by making the main pattern not be quite so centered. If it's the colors, then you could address that by your choice of quilting thread to change either the value or intensity of one of the colors.
I'm trying to remember where I saw it, but there was a quilter who showed a picture before and after of one of her quilts that she just didn't like the value of a couple of the fabrics in the quilt, so she used a thread to quilt it in those sections that was just enough different in value that it changed the apparent value of the fabrics to something that worked better for her.
