First of all, you can draw an oval face outline, which is slightly inclined to convey the feeling of anger. Next, draw a small triangular nose upturned in the center of the face and a mouth under the nose. The shape of the mouth can be slightly exaggerated, with the upper lip upturned and the lower lip bent downward into a "V" shape to emphasize the feeling of anger.
Next, draw eyebrows on both sides of the face. Eyebrows can be turned up to convey anger and dissatisfaction. At the same time, draw deep shadows under your eyes to emphasize the feeling of burning with anger.
In addition, you can draw a few wrinkles on both sides of your cheeks to increase your anger. Finally, you can add some details, such as sharp teeth and prominent muscles, to emphasize the intensity of angry expressions.
In a word, drawing angry expressions needs to highlight the facial features and emotional expression of anger. By using exaggerated shapes and lines and adding details and shadows, you can create vivid and powerful angry expressions.
When drawing angry expressions, you can also consider using different colors and shadows to increase the depth of emotional expression. For example, dark tones can be used to emphasize feelings of anger, or bright red and orange can be used to enhance the intensity of emotions. At the same time, by adjusting the thickness and shape of lines, the characteristics of anger and emotional expression can be better highlighted.
In addition, you can try different painting techniques and styles to express angry expressions. For example, you can use rough strokes to emphasize the feeling of anger, or use delicate lines and soft shadows to increase the softness of emotions. No matter what skills and styles are used, it is important to maintain a professional and high-quality painting style to convey the true feelings and intensity of angry expressions.
