Instead of sleeping I did this in photoshop. "Master study" of a sorts. Can't find who it was who did the original. It is not really a copy because I was trying to find interesting uses of color, rather than spending the time to copy lines and relationships of form. The original featured a different pose, different colors and lizards, but if you'd compare them you'd see the conceptual likeness.
[Edit] I found him! It's Jamie Jones. Fantastic! Credit where credit is due.
