Really nice! I'm going to have to make one now I like yours so well. Wait till you lay out the entire top before you decide as its quite nice 'as is'. If you still feel its too white once the top is done, you could always quilt in the white areas using a variegated thread to add just a little bit of color. I'd probably do a white test block where you've quilted it with the thread and lay it in that area to critique before you commit yourself fully to the entire quilt top.
