Beauty, about 9 x 11". I used watercolor, pastel pencils, NuPastels, carbon pencil, and white acrylic paint. This kind of coat pattern is so lovely -- and takes a lot of work to capture well. What you see here is the result of layering light and dark over one another to get the look of real texture rather than blotches of color stuck onto the surface.
Above, the portrait in an earlier stage, when I had just put down washes of watercolor to establish the base color of Beauty's coat. Below is last night, essentially finished but in need of a few touches; look closely and you'll see that it's missing the texture on the mane-braids and some of the coat pattern on the neck, which I added just after taking this shot.
