I finally jumped into the ring and tried the gems pattern which was shown to us by Kae Yoshino. Eni Oken has also taken this and is making another of her great tutorial e-books. I studied the way she created her gems, and it worked for me. First, I took a photo of the tile before I started shading and weighting.
Then the finished tile.
flux, mooka, Mr. E, crescent moon, tumbleweed, arukas, hollibaugh and echoes and auras around the gems.
