I thought this would be an easy one to do, but I was wrong about that. Following all those curved lines was very difficult for me to do. This is not bad, but it is my third attempt at it. The first was terrible. But I did learn a lot about drawing what the eye sees, and following lines and shadows. Good practice.
This is watercolor and pigma pen in my Aquabee Sketchbook. I enhanced the color a bit in the scan just so the contrast shows up a bit better.
