Step 15: Use the remaining lines as guides to draw the rest of the body. Simply follow the path of the guides and darken the lines to create the Tasmanian tiger's body.
Step 16: Use the line on the left as a guide to draw the Tasmanian tiger's tail. Follow the basic path of the guide but make the base of the tail thicker as you darken the lines.
Step 17 (optional): Erase as much as you can of the initial guide lines for a cleaner look. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines that you may have accidentally erased.
Final Step (optional): Add some shading to your Tasmanian tiger drawing to give it more dimension and volume. Pick the direction of the light source when shading so that the shadows are consistent with it. Add the value lightly at first, then gradually build up to the level of darkness that you want. Vary the pressure on your pencil to get a different degrees of tonal value.
Add a cast shadow underneath. This helps ground the Tasmanian tiger so it doesn't appear to be floating.
You can add even more value throughout your drawing for extra detail. Add the value by using strokes that go in the general direction of the Tasmanian tiger's fur. Shading can be time-consuming, so be patient and take breaks. Using a darker value, add the distinctive Thylacine stripes. The stripes are located mainly on the back, and they get smaller closer to the front. Don't forget to pause the "How to Draw a Tasmanian Tiger" video after each step to draw at your own pace.
