Prompt

Use the uploaded reference image as the exact character identity. Keep facial features, hair, clothing (black fitted T-shirt, black pants), and proportions identical. No changes to appearance.

Scene: Realistic subway platform. Subject stands in the left foreground, body slightly angled right, hands partially in pockets, looking straight ahead. Neutral expression throughout.

Action: Stressed waiting behavior. He paces quickly back and forth then pulls his phone out from his front pocket and looks at the sceen as he turns toward the train at the end. Movements should feel unconscious and stressed.

Background: Train behind him with doors open. A few people enter the train naturally. One person passes in midground. Background motion should be smooth and secondary.

Camera: Static, eye-level, mid-shot. No zoom or movement.

Timing (6–8s):
0–2s stillness
2–6s weight shift + pacing
6–8s stillness

Motion quality: Smooth, physically accurate movement. No jitter, no sliding, proper foot grounding.

Lighting: Overhead fluorescent subway lighting, consistent exposure, no flicker.

Style: Photorealistic, natural, documentary realism.

Negative: No exaggerated motion, no facial change, no eye darting, no camera movement, no distortion, no glitches, no stylization.
