Drawing and painting an adult
portrait can be daunting at first, but it need not be. If you understand
proportions, you can begin to get a good idea of where to place facial
features.
One of the easiest ways to figure out the proportion of a face’s
features is to begin with a basic egg shape and divide it into thirds, starting
at the hairline and ending at the chin. The top third will fall between the
hairline and just below the center of the eyes.
A third of the way down from the
eyes is the bottom of the nose, which lies halfway between the eyes and the
chin. The bottom third is the area between the bottom of the nose to the bottom
of the chin.
Dividing further, the bottom of the lip lies approximately halfway
between the bottom of the nose and the chin. The length of the ears extends
from brow line to bottom of the nose.
Looking straight at the face, if you draw a line straight down from
the middle of the eye, you will touch the edge of the lips. There is one eye
width between the eyes, with the head being approximately five eyes wide. If
you draw a line straight down from the tear ducts, you will touch the outer
edge of the nose.
In profile, the head fits a
square. If you draw a horizontal line through the halfway point of your square,
it will pass through the lower part of the eye, while a vertical drawn through
the halfway point will pass directly in front of the ear.
Not all heads are the same, and head shapes and sizes vary with age.
Use these measurements merely as points of reference to compare to your model
and make adjustments where necessary. For example, your model may have a high
forehead or a wider jaw.

look true to life is that some people make no effort to resemble their
