Step 20: Use the remaining lines and shapes as guides to draw the rest of the greyhound's body. First darken the lines under the head to create the neck. Then darken the outer edges of the initial guides to create the rest of the body. Add curved lines to indicate the dog's chest and the shoulder. Add a curved line at the bottom for the loose skin that attaches the hind leg to the body.
Step 21: Use the long, curved line on the right as a guide to draw the greyhound's tail. Draw the shape of the tail around the guide. The dog's tail should be narrow near the end.
Step 22: 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 greyhound 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. Vary the pressure on your pencil to get different degrees of tonal value. Add the value lightly at first, then gradually build up to the level of darkness that you want.
Add a cast shadow underneath. This helps ground the dog so it doesn't appear to be floating.
You can add even more value throughout your drawing for extra detail. You can actually skip this step entirely if you want an all-white greyhound. Greyhounds' coats have a variety of patterns, so shade yours however you'd like. For a simple gray coat like this one, just use a medium value all over the body. Use a slightly lighter value in certain sections, like the neck and shoulder, to make the coat shiny.
Try to add the value evenly across the dog's body for a smooth coat and avoid a rough, gritty texture. Don't rub the graphite with your fingers. It can ruin the drawing. For smoother graphite, use a cotton swab over it instead. Shading can be time-consuming, so be patient and take breaks. If you have a pet greyhound or a similar breed, try to duplicate its coat pattern on your drawing. Don't forget to pause the video to draw at your own pace.
