Notice the "Top of Head" line. Looking at a live subject, normally the top of the head is an inch higher than the hairline. LITTLE TIP: And when you draw the hair, it is normally an inch higher or more than the top of the head. So cool! The features are divided into thirds. From HAIRLINE to EYEBROWS & TOP OF EARS. The center 1/3rd is from EYEBROWS & TOP OF EARS to BOTTOM OF NOSE & EAR LOBES. The last 1/3rd is from BOTTOM OF NOSE & EAR LOBES to CHIN. Look at the lines and notice how these features are level to their respective lines. Artists and friends, this practice makes perfect. However, some individual faces may vary slightly, but not that much.
