Step 20: Use the remaining lines as guides to draw the rest of the pronghorn's body. Use quick, short strokes along the back of the neck. Darken the outer edges of the initial guides to create the overall body shape. If you made your initial guides too thin or wide, correct them to give your pronghorn the proper body shape. Add a few quick, short strokes on the upper left side of the body for the furry rump and 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 pronghorn 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 a cast shadow underneath. This helps ground the pronghorn so it doesn't appear to be floating.
Add even more value throughout your pronghorn drawing for extra detail on the coat pattern. Use a dark value for the horns and for a patch along the lower jaw. Use a medium value for the top of the head that gradually gets darker along the tip of the muzzle. Vary the pressure on your pencil to get different degrees of tonal value. Leave a strip on the lower part of the face blank.
Use a medium value on the rest of the pronghorn's body except for a couple of stripes on the neck and chest, the tail and the underside. Use a darker value for the hooves too. Shading can be time-consuming, so be patient and take breaks. You can also make the shadows darker to emphasize the structure. It's always a good idea to use reference as you draw. Don't forget to pause the video to draw at your own pace.
