Step 8. Add some shading to offer your horse drawing more structure, dimension and volume. Vary the pressure on your pencil to obtain different degrees of tonal worth. You can leave part of the horse's mane unshaded for a nice-looking shine. Select the direction of the source of light when shading so that the shadows are consistent with it. Shading assists to give your horse drawing more skeletal and muscular structure. It's a good idea to have reference (picture of a horse) available, to get the horse's anatomy as accurate as possible

Final Step. You can add value throughout your horse drawing for extra detail. You can add a solid value like this or draw spots or patches, even stripes! Draw a horn over the head to make a unicorn! Or wings for a pegasus! Have fun with it! If your horse isn't flying, add a cast shadow underneath to ground it.
