2 proportions of the head and face
It’s important to be aware of the proportions of a human face. Of course, they’re only guides – everyone has a different face shape that doesn’t necessarily meet the beauty standard – but it’s essential to know these rules, if you’re going to play by them and break them. I recommend practising with facial proportions, until it almost becomes instinctual to apply them to a portrait piece. I always start with a basic oval and then slowly add the facial features, steadily building up the character’s face.
Slightly tilting the character’s head helps to add visual interest and life to an image
