宠物照片转复古包装对比海报

Turn the pet photo I uploaded into a 3:4 vertical comparison poster. The top half should directly keep the original photo I uploaded, maintaining a realistic photography texture, without changing the subject, redrawing, changing the scene, or altering the composition. The bottom half should convert the pet and scene from the same photo into a vintage matchbox illustration / old pet food packaging / old advertisement poster style. The overall design should use a limited color palette of beige old paper background + faded red + deep blue or dark green, with old paper texture, worn edges, printing grain, and slight registration offset. The bottom half should include a small amount of vintage English titles, decorative text, circular badges, and a bottom slogan. The text content should be automatically generated based on the pet's image, temperament, and scene in the photo, with the overall layout looking like an old packaging cover. Key point: The bottom half should not be too full, it should have borders, white space, and a sense of breathing, overall clean, vintage, cute, and collectible.
