Seedance 2.0 Grandmother Dances Trot Music Video Prompt

Generate a cheerful 15-second senior trot dance video based on the 16-panel storyboard and the character sheet. Keep the same joyful 70-year-old Korean grandmother, with the same short softly curled gray hair, warm smile, natural wrinkles, body proportions, outfit, shoes, and accessories throughout the whole video. She wears a loose beige linen midi dress with abstract black, navy, olive green, and small red brush-print patterns, short sleeves, relaxed A-line silhouette, long pendant necklace, simple bracelet, light socks and comfortable brown flat shoes. Scene: minimal bright indoor studio, warm beige wall, clean floor, soft natural light, small plant on a white side table in the background. Follow the storyboard in order and keep the choreography dynamic but senior-friendly: power opening, walk-in step, side sway, upward point, low trot bounce, half-turn shoulder pose, big arm sweep, gentle spin, small front kick, lean-back wave, tiny jump accent, low bounce pose, confident fist pose, big open celebration, high-leg accent, ending finger-heart pose. The motion should feel cheerful, rhythmic, easy trot dance, 4/4 rhythm, around 105 BPM, bright grandmother energy — not random shaking, not repeated posing, not acrobatic, not too fast.
