Step 15: Use the angled line on the far left side as a guide to draw the first hind leg. Follow the path of the guide and lightly sketch the shape of the deer's leg around it. The top of the hind leg should be a lot wider than the top of the front leg. When you get the shape right, darken the lines. This leg bends a lot more than the front leg too. Use a couple of small, triangular shapes at the bottom to draw the musk deer's hoof and the dewclaw.
Step 16: Use the last angled line under the body as a guide to draw the musk deer's other hind leg the same way. Draw the shape of the leg around the guide. Make the top part wide and the bottom thin. Bend the leg near the top for the joint. Add the hoof and dewclaw at the bottom using small triangles.
Step 17: Use the remaining lines and shapes as guides to draw the rest of the musk deer's body. Simply darken the outer edges of the guides to create the shape of the body. Use short strokes on the bottom for the fur and don't overlap the legs that are on this side of the deer's body.
Step 18: For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines you may have accidentally erased.
Final Step: Add some shading to your musk deer drawing for extra detail. Use a medium value all over the body. Use a lighter value inside the ears, around the eye and on the lower jaw. Use a dark value for the deer's nose. Shade lightly at first and then gradually build up to a darker value. Vary the pressure on your pencil to get different degrees of tonal value.

Draw a thin stripe on the musk deer's chest. As you shade the body, leave some spots blank at the top for the pattern on the fur. Use strokes that go in the general direction of the fur. Shading can be time-consuming, so be patient and take breaks. Different species of musk deer have different coats, so use reference for an accurate depiction.
Use a darker value throughout the musk deer's body to create shadows. Don't forget to pause the video to draw at your own pace. Add a cast shadow underneath to ground the deer so that it doesn't appear to be floating.
