My final design consisted of the aforementioned two layers, with the fish cut out of the second layer. The bubbles were a mix between scoring and cuts and the numbers were cut with the circle inside the 6 and the 9 etched. I also ended up doing a partial scored-outline of some of the fish and bubbles since I thought it looked neat. I was able to create the entire design with Fusion360, using the spline tool to create the cat (although it has a somewhat human looking face). The finished product required a bit of post processing as I chose to glue the cut numbers back in their spots leaving a bit of gap for the underlying black to show through.
