Before learning how to draw faces: some fun facts before starting sketching!
Knowing how to draw nice faces is quite easy if you don't mine practicing a little. In every human face, you should find a forehead (2), two eyes and eyebrows, a nose, a mouth and a chin (3).
Sometimes you can use hair to your advantage and hide a part of the face if you find it too difficult to draw (1)! Just don't overuse this trick. Your readers want to see your character's faces!
The outline of the face is a little irregular. The line below the ears form a "V" shape. The eyes are made of circles and the lips are drawn with ovals. The nose is more tricky.
You can sketch a thin line at the root of the nose and go all the way to the tip of it. You can also draw a small line to show the nares. But in my experience, drawing too much lines to represent the nose is not a good idea. Keep it simple.
Let's try to sketch a simple face. Start by drawing a circle for the outline. Then, try to work around the outline to make it more accurate (see near the ears and the chin). Next, draw the eyes and the eyebrows.
Continue by adding details like the mouth, the nose and the ears. Add some hair and draw the pupils. Here you go! A nice clean face of a cute young boy!
You can easily draw a face with a couple of lines only if you prefer (8) (7). Your character could have a flat head (6) or a narrow one (2). Just use your imagination and try to come up with any ideas that you can think of. From there, you might start creating a new character that you never thought you could ever imagine! Have fun!
