Draw a curved line in front of the foremost leg for the front lower leg on the far side of the Triceratops, and place a sideways pear shape below it for the foot. Draw another line behind the back leg for the shin and foot. Most of this leg will be hidden behind the body and the closer leg. Make a boomerang shape overlapping the larger spike for a brow, and draw an oval just below it for the eye. Add another oval below the front spike for the nostril. Draw two triangles, one above the other, at the end of the snout to make a beak. Finish the face with detail lines around the mouth, nose, and eyes.
On the next page, we'll add some skin features.
