This will be like so many of the other "wonky and wobbely" projects. When it is quilted, it will be lovely and nobody will notice the wonkers and wobblers.
The stars lend themselves to be quilted 1/4" in from the seam. You could do a braid down the pink center with a round-is pattern in the 9-patch. You can start basic and add to it once the basics are in place.
