One of the first things I practiced when I was learning to draw was heads. Not only are they the most distinctive part of the human body, but they’re also the easiest to practice (depending on your skill level and the technique used).

Over the years I've seen different methods for drawing heads, and they all have their advantages, but there are a few things I've learned that can be applied to any method :D

1. The ears are slightly tilted: One of the easiest ways to remember where the chin begins or ends is by using the ears as a reference. Since the ear typically follows the angle of the jawline, it will be slightly tilted; although this can vary from person to person.

2. The eyes are one eye-width apart: Although this will vary greatly depending on the drawing style (and therefore the type of eye drawn), generally the eyes are one eye-width apart.

3. The neck isn’t straight: If you look at the cervical spine in human anatomy, you’ll see an S-shape. If you draw a straight neck, the character will look stiff, like a robot.

+ The head has a brain inside it. It may sound obvious, but I’ve seen many drawings by novices (myself included) where, when drawing their character’s hair, they seem to forget that there’s a brain inside that sticks out. This is very noticeable when drawing the face in profile.
