Here I have re-arranged the blocks to go from light upper left to dark lower right. I have moved some of the circles right out of the block and overlapped some seams. I've made some of the small circles round and added a couple of colors. I'm still not decided on the star sewing but I am going to back all of them with iron-on stabilizer and turn them so they won't be raw edge.
I seem to find the large blue dots rather annoying for some reason so I might change that fabric to something a bit more subtle.
