Step 16: Tighten the shape of Shadow's spikes as you darken the guide lines. The top spike is basically the same, but the spikes on the sides have a more angular shape. Draw them so they angle near the middle as you follow the path of the guides.
Step 17: Draw a few lines inside Shadow's spikes for extra detail. The line for for the top spike is long and shaped like a curved letter V. The other lines follow the basic path of the spikes and should be drawn near the top edge of each spike.
Step 18: That’s it! You now have a nice sketch of a Shadow the Hedgehog from the Sonic video game series and cartoons. You can stop at this quick drawing for a rough, sketchy look, or continue to the step below to go for a more finished look.
Step 19: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for the ink to dry, and then get rid of every pencil mark with an eraser. You now have a finished inked drawing of Shadow the Hedgehog! You can stop here or go to the final step to complete your Shadow drawing.
Final Step: For a completely finished Shadow drawing, you have to color it. You can use markers, color pencils or even crayons! The main color on his head and nose is black. The detail on the spikes and his eyes is red. His muzzle and the inside of his ears are peach. If you don’t have peach, improvise and use yellow-orange or light brown. Experiment! That’s it! You now have a completed drawing of the Shadow the Hedgehog from the Sonic video game series and cartoons.
