How to Draw the Heads in Various Poses
A Rule: The vertical line and the horizontal that make up the face always are perpendicular ( + ) to each other regardless of differing points of view on a head. It also helps to play with your head in front of a mirror, and discover the limits of how far you can move your head.
This diagram shows the positions of the heads in respect to the necks.
The first head of Usagi (Serena) when she's an adult.
The second one is when Usagi (Serena) is 14 years old.
The third is when she is the age of Chibusa(Rini) (8 years old)
The fourth one is when she is the age of Chibichibi (2 years old)
You can see how her faces differ from each
different ages. The youngest person has smaller and more cute looking head
(smaller nose & mouth and eyes are closer to the chin). As a person ages, the head gets bigger, more spacious (wider space
between the eyes and chin), larger noses & mouths. Of course, the hair gets longer with age if not trimmed.
