Until yesterday, I had never painted a living griffin before.
A magnificent specimen named China Blue Rockett posed for me during my hour-long demo on water-soluble colored pencils at Anthrocon.
I used an assortment of Caran d'Ache Supracolor 2 pencils. After a light lay-in, I scumbled a few colors and dissolved them with three Niji water brushes: one filled with clear water, another with a middle gray (the strokes on the sleeve), and another with black.
By juggling the water brushes, I kept the edge around the head soft, so as to suggest the fringe of fur without painting every hair.
