When design elements are arranged symmetrically or asymmetrically to create the impression of equality in weight or importance?

Balance- Balance refers to the distribution of visual weight in a work of art. A feeling of balance results when the elements of design are arranged symmetrically or asymmetrically to create the impression of equality in weight or importance or harmony of design and proportion.

Movement- Visual movement is used by artists to direct viewers through their work, often to a focal area. Such movements can be directed along lines, edges, shapes, and colors within the works, but moves the eye most easily on paths of equal value.

Rhythm: Rhythm is the repetition of visual movement – colors, shapes or lines. Variety is essential to keep rhythms exciting and active, and to avoid monotony.

Unity: Visual unity is one of the most important aspects of well-developed art and is planned by the artist.
Unity provides the cohesive quailty that makes an artwork feel complete and finished.
When all the elements in a work look as though they belong together, the artist has achieved unity.

Contrast- Contrast refers to differences in values, colors, textures, shapes, and other elements. Contrasts create visual excitement, and add interest to the work.

Emphasis- Special attention or importance given to one part or element
in a work of art (e.g., a shape of darker value in a light composition).
Emphasis can be achieved through placement, contrast, color, size, and
repetition, among other means.

Pattern- is simply keeping your design in a certain format. Pattern uses the art elements in planned or random repetitions to enhance surfaces of paintings or sculptures.
