The girl remains perfectly still for a brief beat, maintaining her calm, unreadable detective-like expression and unwavering gaze. She slowly raises her right hand into frame from below with a relaxed, practiced motion. Her wrist rotates naturally as her index and middle fingers approach the cigarette resting on the right side of her lips. Her fingers gently pinch the cigarette without disturbing her facial expression. She smoothly pulls it away from her mouth in one controlled motion, moving it only a few inches to the right side of her face. As the cigarette leaves her lips, her lips close naturally without exaggeration. The cigarette produces a thin trail of smoke throughout the movement. The smoke rises gently upward with subtle turbulence and curls naturally due to ambient air movement. No sudden bursts of smoke occur. Her eyes remain locked in the same direction during the entire action. Her head stays almost perfectly still, with only tiny natural stabilization movements. Her breathing is subtle and realistic. The shot ends with the cigarette held between her fingers just below lip level, close to the right side of her face. Camera remains completely static with no pan, tilt, zoom, focus breathing, or shake. Preserve identical framing, lighting, composition, depth of field, and cinematic atmospher
