Step 10: Draw a small circle inside the head on the left side for the eye. Use the initial lines as guides for placement. Add a line above the eye for the thick brow and skin. Inside the eye, off to the side, draw a tiny circle to represent glare. In the middle, add a big dot for the pupil. Shade the inside of the vulture's eye except for the tiny circle that represents glare. As you shade the eye, use a value that's slightly lighter than the pupil. Add a few lines under the eye to emphasize the bare skin.
Step 11: Use the small arc on the left as a guide to draw the vulture's beak. Darken the initial path of the arc but then extend the line farther down to create the sharp point. Continue to draw the line toward the right to create the mouth. Make the line a bit wavy. The mouth should extend to the inside of the circle. Use the bottom part of the arc as a guide to draw the bottom part of the bird's beak. Add a few more lines under the mouth for extra detail.
Step 12: Draw a square- like shape on the top part of the arc for the second part of the beak. The right side of this shape should curve a little. Add a couple of lines inside, near the left side, for the vulture's nostril.
Step 13: Use the remaining shapes and lines as guides to draw the rest of the head. Follow the basic path of the guides but make the head a little thinner. The head is basically bare, but use quick, short strokes when drawing the shape of it to indicate a few feathers. Add a curved line made up of quick, short strokes to indicate the separation between the bare face and the rest of the head. Draw a thin slit-like mark to the right of the eye for the ear opening.
Step 14: Use the initial curved line as a guide to draw the shape of the vulture's neck. Extend the lines for the head into the neck. Follow the basic path of the guide but make the neck thicker. Use quick, short strokes as you draw the neck to indicate the bird's sparse feathers.
