Marcia- you did something very different with your blocks. On mine, the red is used in both blocks, but you swapped it out of dark purple in one of yours. In doing that, you don't have anything that ties the two together. However you'd need to have another purple block (4 blocks layed out) to really get a feel as it's how those four corners come together that give it the final look.
This is mine, notice that the red is in both blocks, not just one.
