Step 10: Lightly sketch the tiger's eyes inside the head as two small circles. On either side of each circle, draw a small spiky, triangle-like shape for the corners of the eyes. Use the initial construction lines as guides for the size and position of the eyes. When you get the size and position right, darken the shapes of the eyes. The inner corners of the eyes should point down toward the muzzle. The outer corners of the tiger's eyes should point out to the sides of the head. Draw a tiny circle inside each eye to represent glare and a dot for the pupils. Shade in the corners of the eyes using a dark value. Don't overlap the circles for the eyes as you shade in the corners.
Step 11: Add the tiger's nose by first lightly sketching a small V-shaped line inside the muzzle. When you get the placement right, darken the line. Curve the line inward a bit for the nostrils. Draw a wavy line at the top for the edge of the nose. The sides of the nose should curve up above the wavy top edge.
Step 12: Under the nose, draw a horizontal line for the mouth. Curve the line up toward the sides of the initial circle to create the shape of the muzzle. Use short strokes to represent the furry texture of the tiger's muzzle.
Step 13: Draw a series of short strokes along the lower edge of the initial circle to create the chin. The chin should be wide. Add some value to the part of the line that meets the tiger's mouth at the top.
Step 14: Use the arcs on the head as guides to draw the tiger's ears. Darken the path of the guides but make the lines come in toward the head a bit more. Inside each ear, draw a series of strokes to represent the fur found there.
