Use the person in the uploaded photo. Keep the face exactly the same: same eyes, nose, lips, face shape, skin tone underneath the makeup, hairstyle and expression. Do not swap them for someone else.

Give them professional zombie Halloween makeup, like a top special-effects artist did it for a horror film:
- Pale, grey-green skin with soft dark shadows around the eyes and under the cheekbones.
- Fine cracks and dry, peeling patches on the forehead and one cheek.
- One realistic fake wound near the jawline, with dried dark-red edges. Keep it spooky, not gory.
- Slightly cloudy, light-grey contact lenses.
- Messy, dusty hair and a torn, dirty version of the outfit they are wearing.

Setting: a foggy abandoned street at night with a flickering old street lamp behind them and a few dry autumn leaves on the ground. Cold blue moonlight from one side, a faint warm glow from the lamp on the other side.

Style: photorealistic portrait, chest-up framing, sharp focus on the face, shallow depth of field, cinematic color grade, light film grain. The person looks straight at the camera with a calm, creepy stare.

Vertical 4:5 aspect ratio, high detail. No text, no logos, no watermark.
