Step 25: Use the remaining lines and shapes as guides to draw the rest of the Jacob sheep's body. Darken the outer edges of the guides to create the shape of the body. Use a series of short, bumpy lines as you darken the shape of the body to create the fluffy wool. You can also draw the lines for the body farther out away from the guides for thicker wool. Add a few wavy lines within the body for the creases on the sheep's wool.
Step 26: 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 Jacob sheep 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. For a more detailed guide on how to shade, check out this tutorial: How to shade.
Add even more value to your Jacob sheep drawing for extra detail. Use a dark value to shade the horns but use a light value near the tops for shine. As you shade the horns, draw a series of lines along each horn to create ridges. If you make the value on the sheep's horns as dark as the shadows, make the shadows darker.
Use a dark value to draw the markings on the head. Along with the horns, the dark markings on the wool are an unusual characteristic in Jacob sheep. The markings on Jacob sheep always vary, so feel free to make yours different. Use a medium value to shade in the rest of the head and body.
Shade the body using circular strokes to emphasize the fluffy wool. A lot of Jacob sheep are white with dark markings, so you can skip adding the medium value. Shade lightly at first and slowly build up to the level of darkness that you like. As with the horns, if you make the value on the body as dark as the shadows, just make the shadows darker.
Now use a darker value to add the markings all over the Jacob sheep's body. Draw the markings any way you want. A couple of large ones or a bunch of smaller ones. It's up to you! Adding the spots and shading can be time-consuming, so be patient and take breaks. It's always a good idea to use reference for a more accurate drawing.
Add a cast shadow underneath. This helps ground the sheep so it doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
