Open the AI, Command+2 lock, press P to become a pen tool, open the strokes, and select a color to draw line drawings.

First, draw hair. You should exaggerate when you draw. Can't go the same way. Turn off the view alignment pixels, pull out the crank first, and then draw again.

Next, draw her face, which can be exaggerated, and then draw ears, not earrings.

Then draw the neck, you can draw the body where you can't see it, and some wavy parts are also a stroke.
