Step 20 (optional): You can stop here for a sketchy look or erase as much as you can of the initial guide lines for a cleaner look. Don't worry about erasing all of them. It's okay to leave some behind. Also re-draw any final sketch lines that you may have accidentally erased.

Final Step (optional): Add some shading to your bull 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. For a light source that's coming from the top like this one, add darker values underneath along with certain indentations in the body. Take into consideration how light hits the individual form of each body part to accurately depict the shadows. Vary the pressure on your pencil to get different degrees of tonal value.

Add a cast shadow underneath. This helps ground the bull so it doesn't appear to be floating.

You can add more value throughout your bull drawing for extra detail. Bulls have different markings, so you can add patches or spots to your drawing. You can shade the entire body evenly like this for a more solid pattern. Try to add the value smoothly to avoid a rough, gritty texture. You can add a lighter value on certain portions of the bull's body for a sleek, shiny feel. It's always a good idea to use reference for accuracy.
