OMG: Hello, Rainbow!

I'm finally turning my rainbow patchwork slabs into a quilt! I'm making this quilt for Castle Church Brewing Community. I've been playing with layouts for the rainbow; below are my options so far. I started out with the horizontal and vertical rainbows and tried out the diagonal look at the last minute. I'm so glad I did--I put these out on IG, and most people voted for the diagonal layout! What do you think? 

My One Monthly Goal for October is to finish piecing this quilt top. I can't wait to see how it turns out!
