Office Chair Side Painting
The following specific steps can be referred to for painting the side of an office chair:

First, draw a horizontal straight line representing the ground on the drawing paper. By comparing with this horizontal line, sketch the general outlines of the upper and lower parts of the office chair. This step is the foundation for constructing the overall shape of the office chair. Using the horizontal line as a reference helps us accurately grasp the positions and proportional relationships of each part of the chair in space, ensuring that the drawn chair does not appear tilted or out of proportion.
Next, proceed to depict the detailed outlines. The edges of the leather sofa are curved lines. Emphasize the softness when drawing them, and use curved lines for both the outer edges and the inner contours of the sofa to reflect its roundness and fullness. The armrests on both sides are a variant of rectangles. Draw them according to the perspective relationship, following the principle of objects appearing larger when closer and smaller when farther away. The base below is composed of five metal legs connected to wheels. First, draw the metal legs on the left and right sides, and then draw the remaining three metal legs, also paying attention to the perspective relationship to make the base look three-dimensional and realistic.
Then, based on the light source, use a soft pencil (5B) to draw the general dark areas of the entire office chair. After determining the direction of the light source, identify the parts of the chair that receive less light and lightly apply tones with a 5B soft pencil to initially show the light-dark relationship of the chair. After that, use a soft pencil (7B) to draw the overall tone of the leather sofa, as well as the colors of the wheel parts below and the areas where the legs connect to the chair, further enriching the color layers of the picture.
During the in-depth depiction stage, since the leather sofa has a soft texture, the depiction of the turning surfaces in the dark areas should have a natural transition. The depiction of the gray areas should be handled subtly to create a clear contrast between black, white, and gray. Once again, leave reflective surfaces at the joints of each section of the leather on the sofa. The presence of reflective surfaces can enhance the three-dimensionality and realism of the sofa. Use a soft pencil (6B) to further depict the leather on the leather sofa and the upper parts of the armrests on both sides, leaving reflections at the joints of the texture layers of the sofa to enhance the texture and make the leather look more realistic.
Finally, first use a paper stump to lightly smudge the dark and gray areas on the sofa, leaving highlights and reflective surfaces to make the light-dark transitions in the picture more soft and natural. Then use a soft pencil (6B) to deepen the contrast between the dark and gray areas, strengthening the light-dark contrast. The metal legs of the base have reflective properties. After determining the light source, identify the general positions of the dark areas based on the light source, and then observe the reflections on the metal legs. Strengthen the contrast between the gray and dark areas. The highlights on the metal legs are small and sharp. Through the handling of these details, the metal legs can look more glossy and textured.
