Proportion is about the relationship of the size of one element when compared to another element. Proportion is very important when drawing or painting realistically. If the proportions are incorrect, then the resulting image will look less realistic or abstracted.
The proportions used in figure drawing are:
An average person is generally 7-and-a-half heads tall (including the head).
A heroic figure, used in the heroic for the depiction of gods and superheroes, is eight-and-a-half heads tall. Most of the additional length comes from a bigger chest and longer legs.
While much of the subject matter in art has been consistent across time and geography, it is composition and style that define the differences in each art movement. Composition is the placement or arrangement of visual elements or 'ingredients' in a work of art. It can also be thought of as the organization of the elements of art according to the principles of design.
