Step 15: Add a few lines within the shape of the arc at the bottom for the snowy owl's tail feathers.
Step 16 (optional): Add a few lines under the snowy owl's feet to create a rock so that the owl doesn't appear to be floating.
Step 17 (optional): 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 of the final sketch lines that you may have accidentally erased.
Final Step (optional): Add some shading to your snowy owl 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 the value lightly at first, then gradually build up to the level of darkness that you want. As you shade, try to use smooth strokes that go in the general direction of the feathers. Shading can be time- consuming, so be patient and take breaks. Use a darker value on the snowy owl's beak and talons by pushing harder on your pencil.
Male snowy owls have a few spots on their feathers (females have a lot more). You can add some spots to your owl drawing or leave it all white. Don't worry too much about the placement of the spots. Just add them randomly on the body.
It's always a good idea to use reference for a more accurate drawing. Don't forget to pause the "How to Draw a Snowy Owl" video after each step to draw at your own pace.
Snowy owls have bright yellow eyes. If you'd like, you can add some yellow to them.
