Most heads are roughly oval in shape, like an upside-down egg. The halfway rule is a rough guide to where the eyes, nose and mouth should go. It works like this: Eyes halfway between the top of the head and the chin. Nose halfway between the eyes and the chin. Mouth halfway between the nose and the chin. This head is slightly tilted so the lines across will be slightly curved.

When you draw heads, use a light, searching line that you can modify or erase if you need to. The line down the middle helps to track the bridge of the nose.
Lightly sketch in the eyes, nose and mouth. The space between the eyes can alter appearance dramatically. Mouths are also revealing of character
Necks are unexpectedly thick. The bottom of the ears line up roughly with the bottom of the nose, though it can depend on the angle of the head.
