What artistic quality does shadowing mainly enhance in artworks?

Shadowing primarily enhances light and dark contrasts in artworks by creating depth, dimension, and a three-dimensional appearance. By incorporating shadows, artists can emphasize certain areas of a piece, leading to a greater sense of realism. This interplay between light and shadow helps to define forms and shapes, guiding the viewer's eye and establishing focal points within the composition.

Using shadowing effectively can also influence the mood and atmosphere of a piece, as different levels of contrast can convey various emotional responses. For example, harsh shadows might evoke drama or tension, while softer shadows could create a calming effect.

In contrast, the other qualities such as textural elements, overall composition, and color saturation, while important in their own right, do not specifically relate to the primary function of shadowing in enhancing the perception of light and dark relations in an artwork. Textural elements pertain more to the surface quality and feel of materials used, overall composition refers to the arrangement of elements within the artwork, and color saturation focuses on the intensity of color, independent of the shadowing technique's application.
