Step 6: That’s it for the initial sketch! You have the basic shape of Monkey D. Luffy from the Manga and Anime One Piece. Now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 7: Use the initial circles as guides to draw Monkey D. Luffy's eyes. Darken the top and bottom parts of the shapes. Inside each eye, draw a big dot for the pupils.
Step 8: Above each eye, draw a curved line for Monkey D. Luffy's eyebrows. Right where the construction lines intersect, draw the nose as a curved line with a pointy tip near the bottom. The nose should follow the path of the vertical construction line and should end just above the bottom edge of the main circle.
Step 9: Draw Monkey D. Luffy's big open mouth inside the lower half of the head. Follow the path of the bottom edge of the main circle for the top line of the mouth. Then draw the bottom of the mouth using the bottom half of the head as a guide for the shape.
Step 10: Inside the mouth, draw two curved lines, one at the top and one at the bottom. These make up Monkey D. Luffy's teeth. In between the teeth, draw a couple of smaller curved lines for the big tongue.
