Project or sketch the animal onto a shirt with an extrasoft reed charcoal. Then airbrush on a coat of top-binder and press the shirt for five to ten seconds.This prevents the sketch from "blowing off" the shirt and flattens the shirt fibers to prevent overspray from creating "fuzzballs" of paint around your picture.

Using a transparent gray (20 to 30 drops black opaque in 1 oz. water), draw the major outlines and dark areas such as the pupils, eyebrows, and the outer corners of the eyes, edges of the nose, tongue, and chin, and some windblown hairs on the chest.
