Step 1
Start by sketching a "C" shape using an HB pencil.

Step 2
Sketch another "C" shape within the first one.

Step 3
Sketch in the inner ear, which resembles a "G," and add in the rest of the lines.

Step 4
The finished sketch should look something like this.

Step 5
Roughly shade over the entire drawing with an HB pencil, then blend in the shading using a blending stump or cloth.

Step 6
Add in dark lines and shading.

Step 7
Finish up the sketch by erasing the highlights and cleaning up the shading.
