How did the artist use proportion?

manipulating proportion, the artist can make his/her subject seem strong, weak, funny, mysterious, etc. We can exaggerate proportions to emphasize a meaning or an element within the scene. For example, a caricature artist distorts proportion in order to create a stylized image of the subject.
