Step 10: Lightly sketch a small circle inside the head for the eye. Use the construction lines as guides for the placement of the eye. Draw a horizontal line above the small circle for the heavy brow. Darken the small circle to create the shape of the eyeball.
Add some curved lines on either side of the eyeball to complete the exterior shape of the golden eagle's eye. Add a series of lines around the eye for the wrinkles on the bare skin found there. Inside the eye, draw a tiny circle off to the side to represent glare. In the middle of the eye, draw a big dot for the pupil. Shade the inside of the eye using a value that's lighter than the pupil.
Step 11: Use the initial arc as a guide to draw the golden eagle's beak. Follow the path of the guide but make the beak a bit narrower. Continue drawing the line for the beak below the initial arc. Draw the hook of the beak outside of the arc and draw the mouth as a line that stretches toward the horizontal construction line under the eye.
Draw the bottom part of the beak by darkening the lower edge of the initial arc. Use a series of quick, short strokes to the right of the beak to draw its feathery base. Draw a straight line for the bottom part of the beak on the right side instead of quick, short strokes. Draw a short, thick line on the top part of the beak for the eagle's nostril. Add another line to the left of it for extra detail.
Step 12: Use the initial circle as a guide to draw the rest of the golden eagle's head. Simply follow the outer path of the guides and darken the lines to create the shape of the head. Use quick, short strokes as you follow the guide under the beak to create a feather-like texture on the neck. Continue to darken the line farther down than the initial circle to create the neck as well as the head.
Step 13: Use the initial shapes and lines on the right side of the body as guides to draw the golden eagle's folded wing. Follow the basic path of the guides but make the wing bulge out a bit more at the top. Add a few V-shaped lines on the lower right side for the tips of the feathers on the folded wing. Draw a long, diagonal wavy line across the middle of the body for the inside edge of the folded wing.
Step 14: Use the lines under the body on the right side as guides to draw the eagle's first leg. The shape of the leg should be thick at the top. The line for it should start under the very first circle from step 1. Add a few quick, short strokes at the bottom for the feathers, then curve the line back up and under the wing. Use the smaller lines at the bottom as guides to draw the individual toes and talons. Follow the basic path of the guides as you draw the shape of the toes around them. Draw the talons using a couple of curved lines. Golden eagles have massive talons, so don't draw them too small.
