Biker Birthday Cake prompt for Seedance

Copy this prompt

Image-to-video, 9:16, about 7 seconds.
Reference image 1 is the CHARACTER, the rider. Keep their face, hair, skin tone, body shape and clothes exactly as in the image. Adult only.
Camera: first-person view. Two hands at the bottom of the frame hold a round dark chocolate birthday cake with seven tall thin lit candles at chest height. No writing on the cake. Handheld but steady, no cuts.
Setting: a wide, empty, rain-wet waterfront parking lot at night, city lights across the water.
Beat 1 (0 to 2 seconds): the candles flicker; far away a single motorcycle headlight comes straight toward the camera.
Beat 2 (2 to 3.7 seconds): a plain unbranded black sport motorcycle stops right behind the cake; the rider in a plain black full-face helmet turns and pulls the helmet off.
Beat 3 (3.7 to 5.3 seconds): the CHARACTER's face is revealed, they tuck the helmet under one arm, smile, lean in and blow out the candles.
Beat 4 (5.3 to 7 seconds): the picture turns black and white and slows almost to a freeze-frame on the smiling face above the smoking candles.
Audio: a motorcycle engine arriving, then a soft warm instrumental. No voices, no singing.
Photorealistic. No text, no captions, no brand names or logos on the bike or helmet, no watermark.
