Step 15: 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 grizzly bear drawing for extra detail. Use a dark value for the ears. Vary the pressure on your pencil to get different degrees of tonal value. Shade using tiny strokes to emphasize the fur's texture. The strokes should go in the general direction of the fur. They should radiate outward from the middle. For a more detailed guide on how to shade, check out this tutorial: How to shade.
Separate each individual stroke a bit so that the white of the paper comes through and creates a more fur-like texture. Use a dark value for the fur around the eyes too. Notice how the strokes for the fur wrap around the shapes of the grizzly bear's eyes. Add the value very lightly at first, and then gradually build up to a darker value. Use a dark value for the nose. Leave a thin strip at the top blank to represent shine.
Continue to add more strokes on top of each other to build up the layers of the grizzly bear's fur. Shading can be a very slow process, so be patient and take breaks. Use more value on the nose to make it even darker, especially the nostrils. Don't push down too hard with your pencil though. The graphite can become shiny, and you might tear the paper. It's always a good idea to use reference for a more accurate drawing. Don't forget to pause the video after each step to draw at your own pace.
