If you are serious about wanting to - break it up a little - I have a quick idea for even a finished quilt. Get a roll of fusible bias tape in a color that would work for your quilt - lay it out and see how you can use it as very narrow strip sashing that you can fuse on and applique with a twin needle to give some definition and added structure to your design.
I really like the use of the bright colors, but as I am into adding embellishing to my quilts, this might help you like your quilt more. It is an add-on that can even be added-on to a finished quilt.
I don't see a close up but depending on what thread and design it is quilted with - it might be possible to use a #12 or # 30 weight decorative thread in a open decorative stitch to make definition lines.
I guess your quilt really speaks to me as having more potential for play. PM me if you have any questions about pursuing any of these ideas.
