Features: Sketching and rendering plaster head portraits is a mandatory course for understanding the anatomy and structural composition of the human head. It enables artists to gain a clear understanding of the internal structural relationships of the human figure before beginning live modeling, and through plaster head portraiture, to develop further the ability to discern and express black, white, and gray relationships. It also plays a role in cultivating aesthetic and compositional skills. The expressive forms of basic sketching are roughly divided into three categories: line, line-and-plane combination, and chiaroscuro. The first two generally focus on depicting the structural composition of the subject, while the latter often emphasizes the rich relationships between black, white, and gray, creating a strong sense of realism and spatial depth. However, regardless of the approach, these expressive forms must be grounded in rigorous and accurate structural relationships. Identifying the structural relationships is the foundation and prerequisite for completing a work well. In general, we start painting with line-based techniques because lines are more concise and direct, allowing us to quickly grasp the structural relationships of the subject. Therefore, some refer to sketches that primarily use lines and focus on analyzing the structure of the subject as structural sketches. On the other hand, sketches that emphasize the rich variations in black, white, and gray relationships and highlight the interplay of light and shadow are called tonal sketches. However, there is no inherent hierarchy between the two; they simply differ in focus. Whether it’s structural sketches or tonal sketches, the premise is always the structure of the subject, and light and shadow must exist based on the structure. Beginners naturally start by understanding the structure of the subject, meaning they must first learn to use lines. Beginners are very prone to falling into the trap of "over-focusing on." Long, straight lines can help reduce such mistakes and enhance their sense of volume. When learning, the understanding of objects should be more rational—analyzing the relationships between volume and planes, identifying key "points," and it somewhat resembles memorizing formulas for the human head." But this is very important because the structure of the human head is the same, with only differences in proportions. These "formulas" can help beginners better understand the overall structure and the transitions between planes. However, painting should ultimately be grounded in a perceptual level. Beginners should first scientifically observe and analyze the subject under the guidance of a teacher, seeing through the phenomenon to the essence, but what is ultimately presented to the audience should be a phenomenon that incorporates the essence of the object, summarized and processed by the artist. From rationality to perceptual understanding is the process that beginners should follow in their journey from recognition to expression.
