Un zombi de cuerpo entero centrado en un encuadre vertical

Use the uploaded image as the exact visual reference. Convert the composition from landscape to a vertical 4:5 image, 1080x1350. Keep the same zombie character, clothing, face, pose, lighting, color palette, and art style. Keep the character centered and fully visible from head to feet. Do not redesign the character, do not change the identity, and do not add extra people. Reframe by removing excess background from the left and right sides. Extend the existing background naturally above and below only as needed to reach 4:5. Preserve the original scene, perspective, and atmosphere. No text, logo, watermark, border, or UI. No stretched, squashed, duplicated, or cropped body parts.
