Use the uploaded photo as the exact identity reference. Keep the face, skin tone, hairstyle, accessories, and outfit exactly the same. Create a vertical full-body image of the real person standing beside their {argument name="twin style" default="ink-twin doodle"}. The real person should look photorealistic with a playful, slightly embarrassed expression and a natural pose. The {argument name="doodle type" default="ink twin"} should be a rough black charcoal sketch on a clean white or light gray wall, matching the person's hairstyle, outfit, and pose only as a silhouette, but with exaggerated, chaotic energy. Add a few simple doodle effects like {argument name="effects" default="motion lines, stars, or hearts"}. Use soft natural daylight with a clean minimal background. Do not change the person's appearance or outfit. Do not make the twin a real person, colored cartoon, or flat shadow. Avoid repeated poses, bad hands, extra limbs, clutter, text, or watermarks.
