Realistic Pen Drawing of Seated Male AI Image Prompt

Using realistic pen technique, with fine pen lines and cross-hatching to achieve complete black-white-gray transitions, accurately reproducing the texture and light-shadow details of the figure and environment. The subject is a young male (refer to the provided image for the subject), sitting relaxed with his left hand supporting on the ground beside him, wearing a Japanese-style simple loose hoodie and straight-leg pants, with a canvas bag placed at his feet. Through the logic of sparse lines on light-receiving surfaces and dense lines on shadow surfaces, clearly present the folds, shape, and corresponding light-shadow effects of the clothing. The background is flat ground with short grass, a broadleaf tree beside, and a winding river in the distance. The overall line density of the background is lower than that of the figure, creating a natural contrast of solid and void to highlight the figure. Set a soft light source directly in front, control the overall light-dark contrast to be soft, and use different depths of hatching to create a three-dimensional effect for both figure and background, evoking a calm, introspective, and relaxed atmosphere. [Note: For the reference image, only refer to the facial features, gender characteristics, and age of the figure. Do not refer to emotions, expressions, clothing, accessories, or surrounding environment.]
