A good drawing is the foundation for all art forms because it teaches the artist essential skills such as composition, form, and perspective. These skills are important for creating art in any medium, whether it be painting, sculpture, or graphic design. Drawing allows artists to develop their observation skills and to understand how to create the illusion of depth and space on a two-dimensional surface. It is often used as a starting point for more complex works of art, as it allows artists to plan out their ideas and experiment with different compositions before committing to a final piece.
