Step 15: Use the arc on the left as a guide to draw the first ear. Darken the basic shape of the arc but make the tip pointier. Use the arc on the right side as a guide to draw the red deer's other ear the same way. Add a few short strokes inside each ear for the fur found there.

Step 16: Use the main circle as a guide to draw the rest of the red deer's head. As you darken the top part of the head, dip the line a bit in the middle. Draw a line from the nose to the eye on the left to finish the muzzle. Add a few short strokes on the right side for the coat. Draw more short strokes under the head for the loose skin found there.

Step 17: Use the curved line on the right as a guide to draw the first antler. Darken the path of the guide. This will be the bottom edge of the red deer's antler. Near the top, draw a thin, curved spike for the first branch on the antler. Pay attention to how high this branch is. Make it as tall as the guide. Near the middle of the guide, draw another thin, curved spike for another branch. At the bottom of the guide, right on top of the head, draw another spiky branch the same way.

Step 18: Continue to use the line on the right as a guide to draw the first antler. Draw a thin, curved spike between the bottom two for another branch on the red deer's antlers. Make the base of the antlers thicker in between the branches while following the path of the guide. Use the tip of the line as a guide to draw the highest branch. Add another spiked branch on the left side and attach it to the base at the bottom. Leave a gap between these top two branches. Sketch lightly at first and only darken the lines when you get the shapes right. Add a final branch at the top between the gap of the first two branches.

Step 19: Use the curved line on the left as a guide to draw the red deer's other antler in a similar way. Draw a thin, curved spike along the bottom part of the guide for the antler's first branch. On the right side, draw a line that's somewhat parallel to the guide to make the antler thick. Toward the top, curve the line away from the guide farther to the right. At the top of this line, draw two thin, curved spikes for more branches. The prongs on this forked branch should be pretty close together.
