Step 20: For a cleaner look, erase as much as you can of the initial guides. 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 dinosaur drawing for extra detail. Nobody is exactly sure what velociraptors looked like, so shade yours any way you'd like. You can even color it! For this look, add a speckled pattern by alternating between dark values and blank sections. Alternate between a dark value and a blank spot on the dinosaur's individual feathers for a striped pattern For a more detailed guide on how to shade, check out this tutorial: How to shade.
Vary the pressure on your pencil to get different degrees of tonal value. Use a medium value for the legs and underside of the body. For an easier drawing, just use a medium value for the whole body. You can use modern-day birds of prey and raptors as reference when you shade for inspiration. Add the values lightly at first and slowly build up to darker levels. Shading can be time-consuming, so be patient and take breaks.
Add extra value to the velociraptor's body for some shadows. Use a dark value for the claws but leave a thin section blank for shine. Add a cast shadow underneath. This helps to ground the dinosaur so it doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
