You need to doodle your way through lots of faces until you get the hang of drawing them the way you like them. I haven’t quite figured them out yet, but I’m getting there. Minor variations on a theme help me understand things better. This must be why there are lots of classical music pieces that sound alike – composers figuring things out, too.
I like the simple style I picked up from Sachiko Umoto’s Illustration School: Let’s Draw Happy People. Two dots, a nose, a mouth. That’s all we need. Actually, people want to see faces so much, you can pretty much pick anything with two “eyes” and bilateral-ish symmetry.
It’s fun to draw faces. They make me happy even if I don’t fill in the rest of the figures.
Practice will help me learn how to draw better. Faces, then torsos, then legs, then arms, then hands.
