# Main Prompt - Idol Full-Body Groove (Classroom Ver.) shot: type: r2v aspect_ratio: "9:16" camera: fixed, single continuous shot, no cuts framing: character occupies lower two-thirds of frame, medium shot from waist up, full arm extension should remain within frame character: reference: use attached reference image for full appearance (face, outfit, colors, proportions) art_style: preserve original character art style / cel-shading from reference, do not blend with background style motion: choreography_style: J-pop idol full-body groove - point dance hand accents combined with strong hip/chest movement, wide arm throws, and traveling footwork; energetic and dynamic, not restrained ground_rule: only beat_7 involves a brief hop; all other beats keep at least one foot grounded at all times, weight shifts through full leg and hip engagement rather than staying stiff sequence: - beat_1_2: wide step to the right with full weight transfer, both arms throw outward and up into a diagonal "V" shape, chest pops forward on the accent, hips follow the arm direction - beat_3: arms whip back down and across the body, torso twists with the motion, right hand ends in a sharp point toward the camera - beat_4: quick recover to center, small chest pop plus hip bump to the right on the offbeat - beat_5_6: mirror of beat_1_2 to the left - wide step, arms throw diagonally the other way, hips follow, chest pop - beat_7: energetic accent beat - one clean, controlled hop in place (both feet leave the floor briefly together, land together), arms pump downward on the landing for emphasis; this is the single high-energy peak of the sequence - beat_8: land, feet planted, body drops into a grounded groove - knees bent, torso rolls in a small body wave from chest to hips - beat_9_10: double point combo - right hand points forward with a step forward, immediately followed by left hand pointing forward with weight recovering back, hips keep swaying underneath - beat_11_12: full-body spin-out - a quick 180-degree turn using a pivot step (feet stay grounded, one foot pivots), arms sweep out during the turn, ending facing camera again with both arms opening into a wide "sparkle" gesture - loop: sequence repeats seamlessly from beat_1 tempo: upbeat, driving, high-energy idol-pop tempo; gestures are large and confident, transitions snap rather than drift motion_notes: no slow motion, no speed ramping, natural constant playback speed throughout; beat_7's hop must read as one clean controlled jump-and-land, not repeated bouncing; all other beats stay grounded with movement driven by hip/torso/arm amplitude rather than vertical lift setting: location: after-school classroom, empty of other students time_of_day: late afternoon / early evening, warm light through windows environment_details: rows of desks and chairs as soft silhouettes in the background, chalkboard
