I also fell in love with the colors and made a OBW.. it is hanging on the felt until I am pleased with the color arrangement.....just waiting for the right look. I love it! So soon I will be putting those blocks together. I am sure yours will turn out GREAT. I added a few Hollow Cubes in it to give it a surprise look....that was more of a challenge, because you need to give it dimension.
Good luck with yours....post when you have it completed....can't wait to see it. No 2 are ever alike, so my quilt won't look like yours even tho we used the same material! OBW!
