We’ll start with ‘stick-figures’. Practice trying to get the general proportions right. Though exaggerate the size of the head. This allows you to get facial expressions that can be easily seen.

‘Body language’ is an important part of the figures. Exaggerate the expression. Can you name the expressions shown here?
Copy these, then do a dozen ‘body-language’ expressions of your own, naming the expression.

Then add ‘flesh & body’, again showing ‘body-language’, exaggerating the movements.
