Below you will find a favorite little inspirational video I created that shows you how fun and easy it is to draw a face. Notice I said FUN and EASY. The reason why it is fun and easy to draw a face is because I used a simple formula all artists apply to face making.
Just a simple exercise of circles can help you "think" about the arrangement of the human face. A circle for the head, nose, lips, eyes, chin and cheeks. Of course your faces can't all be round! But what fun it is to start with a circle before working with ovals or even squares.
A little bit of a pointed chin here above, and this is just a play time drawing with one graphite pencil. Some concentration in this sketch is on the angular shapes of the face, but not too dramatically different from the first sketch, at least not in principle.Try it for yourself!
