Howling Wolf is one such illustration and at the same time it test hair detail. Start your rough outline of the wolf's body by tracing the spending stand way posture, with arched head. Flick in the tale, ears and snout with gentle lines.
Now make it's mouth wide open for the howling effect, with fangs important. Put its long, bushy smackdown in the background for balance. Slowly refine these rough sketches into definite lines, adding texture for fur.
Lastly, underline areas to create a 3D effect and add moonlight conversation pieces as well as shadows for atmosphere. The secret to creating a truly great work of united art is in watching real wolves and their full-of- feeling body language.
