Unity

Unity is essential in art. It is the harmony that exists in a composition. Three ways to achieve unity are by use of proximity, repetition, and continuation. 

Proximity

Proximity is easily described as nearness. The eye is drawn to the proximity of objects and sees them as a whole before it sees them separately. In the picture below from Tales of Symphonia, the five characters are standing close together in the center of the picture. The viewer first sees the group together and then is able to distinguish each character.

Repetition

Repetition is an element that recurs over and over. Sheena, from Tales of Symphonia, is surrounded by lines of cards in the air that repeat over and over in a consistent pattern.

Continuation

Continuation is a line that allows the eye to move continually from one area to another. The lines of the rocks above the boy flow to the line of the bridge and onto the next rock, allowing the viewer to see everything very smoothly.
