Step 6: Inside the body near the left edge, draw a curved line that resembles the letter J as a guide for Dexter's arm. The line starts right below the circle and is a tiny bit longer than the body.
Step 7: Draw two shapes that resemble trapezoids under the body as guides for Dexter's feet.
Step 8: That’s it for the initial sketch! You have the basic Dexter shape, so now go in and tighten your drawing of this Dexter's Laboratory character. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 9: Darken the line for Dexter's nose. Draw a couple more curved lines under the nose to make the mouth.
Step 10: Thicken the arcs that make up his eyes and the horizontal construction line to create Dexter's thick-rimed glasses. Inside each eye, draw a small half circle and shade them in. These are Dexter's pupils.
