Nice geometric design. Does it bother you because it is only 2 colors? If that is it, I don't know what you can doth other than taking it apart in moderate size sections and adding other blocks with additional colors. But personally, I would leave it as is and have it quilted in dark blue thread in a fairly elaborate design--which will add a third dimension and perk it up. Appliqués are another option but I hate to appliqué so that wouldn't be an option for me. The only other idea that occurs to me is to switch out the borders to a different fabric that has a bold, colorful print.
