Step 10: Lightly sketch the eyes inside the head as two small ovals. Use the initial lines as guides for placement. When you get the position and size of the jackal's eyes right, darken the lines. Make the sides pointier. Draw a line inside for the eyeball and a line underneath for extra detail. Draw the eye on the right the same way but make it narrower. This eye should fit between the vertical guide line and the right edge of the circle.
Step 11: Inside each eye, near the middle, draw a dot for the pupils. Next to the pupils, draw a tiny circle for highlight. Draw a series of short strokes above each eye for a bit of fur. Add some strokes under the jackal's eyes for more fur.
Step 12: Inside the muzzle, near the right side, lightly sketch a small oval as a guide for the nose. When you get the position and size of the oval right, darken the edges. Draw a couple of tiny ovals inside the nose and shade them in for the nostrils. Curve the sides of the nose so that they to connect to the nostrils. Add a line above the jackal's nostrils and use short strokes to darken the top edge of the nose.
Step 13: Draw a line below the nose for the jackal's mouth. On the right, the line curves up along the initial circle. On the left, the line stretches all the way to the edge of the initial circle.
Step 14: Use the bottom edge of the initial circle as a guide to draw the jackal's chin and lower jaw. Use a series of short strokes along the basic path of the circle's edge to create the shape of the jaw. Draw a sloping line from the nose to the eye on the left for the top of the muzzle.
