Vintage Halloween Poster Transformation (#nb_25)

{
    "prompt": "Transform the uploaded photo into a vintage Halloween poster. Preserve the same person, face, hairstyle, pose, and outfit colors — do not replace the subject or change their skin tone or body shape. Add a classic black witch hat (slightly tilted with a brass buckle) and a flowing black satin cape with natural folds. Have the subject hold a glowing carved jack-o'-lantern, with warm candlelight illuminating the hands and chin. Create a diagonal split background of dark teal and burnt orange, with subtle mist and fine spider-web texture; place a full moon at the top-right and bat + ghost silhouettes at the top-left as small accents. Compose a 2:3 vertical poster, subject centered, cropped around the knees. Add an aged paper border, light film grain, and studio lighting (soft key from front-left, gentle rim from back-right). Add a bold vintage serif headline \"Halloween Night\" at the top and \"Trick or Treat\" at the bottom, off-white with slight emboss/outline; keep text crisp and readable. High detail, clean image, no watermark. Do not change the outfit's original colors or design; do not cover the face.",
