Okay, Lynley, this is a Gee's Bend meets Liberated Amish class so it's time to play. I seriously want you to cut apart your quilt top that you're not happy with. It's the big blue rectangles that aren't working - so cutting them up reduces their impact. Plus, the pink triangles are the marvelous bit and this way they'd stand out. You can cut it apart any way you want - just don't use the seam ripper. Here are a couple of ideas. Straight lines:
Then you'll have some interesting pieces to play with. And yes, you're "allowed" to cut the new pieces down further - depending on how you cut you could end up with globs of seam allowance that might be better whacked off.
Add another really strong color and play with sashing idea or setting squares or who knows what you'll come up with. Cut them apart, play and if you have any questions, post another pic of the new pieces and we'll do this step by step!
