Step 6: Draw two long, angled lines under the second circle as guides for the musk deer's hind legs. Notice how these lines bend. The line on the right should bend near the middle and slope to the right.
Step 7: Draw two curved lines that connect the circles on the right as a guide for the neck. Connect the circles in the middle using two longer lines to complete the guide for the musk deer's torso.
That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 8: Inside the head, near the top, right side, lightly sketch a small circle for the deer's eye. When you get the size and position right, darken the lines but make the sides pointier. Add a curved line at the top and a broken line at the bottom for the eyelid and fur. Inside the eye, off to the side, draw a tiny circle for a highlight. In the middle, draw a big dot for the pupil. Shade in the rest of the musk deer's eye but don't overlap the tiny highlight circle. As you shade the eye, use a slightly lighter value near the bottom for a more rounded look.
Step 9: Lightly sketch a small circle on the tip of the muzzle for the musk deer's nose. Darken the shape when you get the position right. Use short strokes for the fur at the top. Curve the left side inward to create the deer's round nostril. Make the bottom part of the nose thinner as you darken the lines.
