Just as in the previous post, a decision is made to post the sketch of the tessellation rather than the attempt at re-doing it. I did a Google images search while I was trying to re-draw this Manta Ray Tessellation and came across a pretty spectacular image, quite similar in colour and feel. Blew me away. For some reason, some drawings look better all scratchy and textured. This is one of them.
