Step 16: Use the main circle as a guide to draw the rest of Toothless' head. Follow the basic edge of the circle as you darken the line but don't draw the top part. Instead, draw a broken line that connects the arcs at the top. Also draw a small row of scales using tiny arcs at the top of the head. Use the vertical line to help with placement.
Step 17: Darken the lines under Toothless' head but make them curve more to create the neck.
Step 18: That’s it! You now have a nice sketch of Toothless from How to Train Your Dragon. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the step below.
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 Toothless! You can stop here or go to the final step to complete your Toothless drawing.
Final Step: For a completely finished Toothless drawing, you have to color it. You can use markers, color pencils or even crayons! Toothless is pretty easy to color. He's basically black all over, but you can use a lighter shade of black around the head to give it more dimension. The eyes are light green, and the inside of the mouth is pink and brown. That’s it! You now have a completed drawing of Toothless from DreamWorks' How to Train Your Dragon.
