Preserve the person exactly as in the original real photograph. The person must remain fully photorealistic, including the face, body, pose, hairstyle, clothing, proportions, skin texture, and natural photographic lighting. Do not illustrate or redraw the person.Replace the entire background with a pure white base and redraw all environmental elements using green monochrome hand-drawn speed-sketch linework. Use green contour lines only, no fill colors, no shading, no gradients, no painted textures.The background linework should feel loose, casual, spontaneous, and slightly imperfect, like a hand-drawn architectural sketch or quick pen drawing.The photographed person should sit clearly in front of the illustrated background, with strong visual separation between the real subject and the sketch environment. Mixed-media style, real photography combined with hand-drawn green line art. Do not let the sketch lines overlap or cover the person. Do not change the subject’s pose, clothing, facial features, body shape, or proportions.
