Thank you Mike and Stuart. In the end I decided to add the thin walnut wafer (same thickness as the layers) to the bottom after it was off the lathe. I think the walnut top certainly added to the effect so the bottom should do the same. It is in clamps now so I will wait until morning to clean it up and start the finish. During the final re-shape I turned it down slightly to take off the white (maple) area that you can see in a couple of photo's back. I found your eye drawn to that area as it was bright.
