A sketch why did the artist choose to use shading in this drawing

Without a specific example of a drawing, I will provide a general explanation as to why an artist might choose to use shading in their drawing.

The artist probably chose to use shading to add dimension, depth, and realism to their drawing. Shading can create the illusion of light and shadows, making objects appear three-dimensional on a two-dimensional surface. It helps to define the form, contours, and texture of objects, giving them a more tactile and realistic appearance.

Shading can also be used to create a sense of mood or atmosphere in a drawing. Depending on how the artist applies shading, they can convey different emotions or convey a specific time of day or setting. For example, heavy shading might be used to create a dramatic or mysterious mood, while light and delicate shading can evoke a sense of tranquility or peacefulness.

Additionally, shading can help to establish the focal point or create a visual hierarchy within the drawing. By using stronger shading on certain areas and more subtle shading on others, the artist can guide the viewer's eyes and draw attention to specific elements or details.

Overall, the artist chooses to use shading in a drawing to enhance its visual impact, bring it to life, create a sense of depth and realism, convey mood or atmosphere, and establish a focal point or visual hierarchy.
