Notes on facial features – mouth

  •  Start with the shaped centre-line. (Consistent for all people due to the way lip is formed in pre-natal development)



  • The centre-line is the darkest part of the mouth.
  • The plains of the upper lip face downwards (in shadow).
  • The plains of the lower lip faces upwards (lit).
  • As you go towards the sides of the lower lip, that dark lip edge gets softer. The lip protrudes but flattens out towards the sides so the shadows are not as strong.


  • The teeth/jaw area is actually quite strongly curved (compared to say, the brow area). Take note of this when working with the lip in perspective.
