Thickness of the neck

However you represent the head, whether it is relatively simply yet characteristic, or incredibly refined, you can now identify the start of the neck from the chin. The digastric plane is the bottom plane, it gives the head thickness. It will be useful when drawing the head from other angles - the biggest hurdles is working in a flat 2d plane while seeking to depict volume.

The gesture from the chin to the bottom of the neck is curved and downward. It is better to make the neck a little too long than too short. You then come from the bottom of the skull, the key here will be not to make the back of the neck too skinny.

Notice that the neck starts very low in the front and very high in the back. Think of your shirt collars, it sits high in the back and low at the front.
