The first thing I had to do was figure out how to do an iridescent surface on the cake. It took a lot of luster dust and layering, but when I was done I was happy with the variations in color and texturing that the layers of color had created.
Then I added the pewter colored fondant pieces that I made using some molds from architectural elements. Those were painted with more luster dust, and finished off the look. I made the patterns on opposing sides of the cake different but connected them all to create a framework that's obvious as you walk around the cake.
The molds that I used on this are all available in my online shop:
