I finished the rest of the limbs and looked at them carefully for shadow and light which would weave them together and create a 3 dimensional effect. the lower limbs become a bit darker and rougher as they come toward you.
I have been painting in watercolor for more than thirty years. The medium still holds the same fascination that it held for me the very first time I carefully wet the paper, applied a small amount of color, and instantly blotted it with the tissue clenched in my left hand. My students to this day say that when the left hand goes in my pocket, the painting is going well.
