Please see the drawing tutorial in the video below
You can refer to the simple step-by-step drawing guide below
Start the first step by drawing the head and body guides, then the face guides.
Using the guides you just created, draw the shape or structure of Gon’s face. Use the same liner to form the spikes as you can see them in small and large blocks.
Add an inner liner to the hairstyle to separate the hair from the face. Then, line the hairline along the eyebrow. You can then use the facial guides to draw out shapes for the eyes, mouth, and ears. Don’t forget the details to the ears and face.
Hair, face, and expression are all fine. Now you can start drawing the body starting with the neck. Move on to drawing the shoulders and arms, followed by the torso. Draw the coat zipper line and then continue to step five.
Draw the body and then the legs. Then you will draw the pocket lines and collar details. Clear the errors and all the causes you are done.
The line art should look like the drawing you see here. Color Gon in and you’re done. Color him.
