竖版上下对比红线手绘写实锚点海报

Turn the input photo into a vertical 3:4 top-bottom comparison transformation poster without watermarks. The upper half, approximately 45%, retains the original photo's complete composition, subject, action, perspective, and real light; the lower half is a hand-drawn red-line environmental sketch of the same framing. The lower half converts the buildings, streets, plants, landforms, objects, transportation, or animal environment in the photo into brick-red to ochre-red monochromatic lines made with thick markers/crayons on warm white blotting paper. The lines should have variations in pen pressure, breaks, retracing, cross-hatching, dryness, and a small amount of ink bleeding, retaining key contours and spatial relationships while removing irrelevant details and leaving broad continuous paper white. Select only one subject from the original image with the most narrative role as a real photo anchor—a person, animal, vehicle, food, or object—and retain its real texture, color, material, posture, and natural shadows in the lower half, letting it make contact with the hand-drawn ground or environment, as if stepping out from the red-line scene. The number, identity, action, scale, and position of the anchor must be consistent with the upper half. Do not turn the subject into a cartoon, do not add fantasy characters, fictional landmarks, fake text, brands, watermarks, original image or AI image tags, and do not apply full-image filters or smooth vector strokes.
