Step 20: Use the wavy line on the left side as a guide to draw the jerboa's tail. Follow the path of the guide as you draw the tail around it. Keep the lines for the tail close to the guide so that you get a thin tail shape. Use a series of short strokes around the end of the guide for the bushy tip of the tail.
Step 21: 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 jerboa drawing for extra detail. Use a smooth, medium value for the main part of the ears. Use a darker value along the edges. Shade the rest of the body using a medium value. As you shade the body, use strokes that go in the general direction of the fur. Separate each individual stroke a bit so that the white of the paper comes through and emphasizes the fur-like texture.
Vary the pressure on your pencil to get different degrees of tonal value. It's always a good idea to use reference for a more accurate drawing. Use a darker value along the bottom of the jerboa's body for shadows. Use smooth shading for the tail and legs. The tip of the tail should have a darker value. Shading can be time- consuming, so be patient and take breaks.
Add a cast shadow underneath. This helps ground the jerboa so it doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
