Step 15: Use the line on the far left side as a guide to draw the Siamese cat's first hind leg. Sketch the leg lightly as you follow the basic path of the guide and only darken the lines when you get the shape right. Draw the toes at the bottom using a couple of curved lines. Bend the leg near the middle to indicate the joint. Use quick, short strokes mainly on the top part of the leg. The top part should also be a lot thicker than the bottom.
Step 16: Use the remaining line under the body as a guide to draw the other hind leg. This leg should be bent more than the others. The joint should be close to the top. Separate the individual toes on the cat's feet using a couple of curved lines. The top part of the leg should be wider than the bottom.
Step 17: Use the remaining lines as guides to draw the rest of the Siamese cat's body. Simply darken the outer edges of the initial guides to create the shape of the body. Use quick, short strokes on the left and underside of the body to create shaggy fur. If you made your initial guides thinner or wider, now is the time to correct them to give your cat the proper body shape. Use the line on the left side as a guide to draw the tail. Use quick, short strokes along the guide to create the furry tail.
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 throughout your cat drawing to give it the distinct Siamese look. Use a dark value for outside of the ears and a lighter value for the inside. Vary the pressure on your pencil to get different degrees of tonal value. Use a dark value for the face as well, including the nose. Use strokes that go in the general direction of the fur. Continue adding the dark value until the entire front part of the Siamese's face is covered.
Use a lighter value as you reach the top and sides of the head and the bottom part of the muzzle. Add a dark value to the tail too. Use vertical/diagonal strokes as you add the value to the tail. Use a dark value for the legs as well. The value should be light at the very top and gradually get dark. Continue adding the dark value to all four legs. Remember to use strokes that go along with the fur. In this case, mainly vertical strokes.
Now shade the rest of the Siamese cat's body using a light to medium value. You can also use this tutorial as a template for any cat and shade it how you want. Make it an all black cat, a white cat or any pattern you want! For the traditional Siamese look, cover the entire body with a medium value using horizontal strokes.
Add some shading to your Siamese cat 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. The value of the shadows should be darker than the body but not as dark as the face or limbs. It's always a good idea to use reference as you draw.
Add a cast shadow underneath. This helps ground the cat so it doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
