Mirror Selfie Pose Transition Video Prompt

Prompt: Keep the same face, hairstyle, white tight long-sleeve top, black bottoms, phone, flash light, mirror, and dim room environment completely consistent. Video about 5 seconds, maintain mirror selfie composition, do not change camera position. Opening maintains original leaning pose: the hand holding the phone on the left side of the frame continues to be raised beside the face, phone always facing the mirror, flash light stays on; the right arm continues to support the bed/soft cushion as body support. Seconds 1-3, use the supporting arm to push up, letting the upper body gradually rise from the clearly sideways pose, while the waist tightens, hips clearly push to the left side of the frame, chest and shoulders slightly rotate in the opposite direction to the right, forming a more pronounced S-curve. Legs keep original stance, only shift weight with the hips, no complex stepping. Short hair naturally sways slightly with the movement. At the same time, the hand holding the phone turns the phone angle slightly inward, but does not block more of the face; her gaze initially falls near the phone screen, then slowly moves to the camera in the mirror. Seconds 3-4, she gently lifts her chin, head tilts slightly to the right side of the frame, a faint confident smile appears at the corner of her mouth, keeping a cool rather than cute expression. Final 1 second, she stops pushing up further, lets her body lean slightly closer to the mirror again, hips maintain the new shifted weight, shoulders and waist form a clear opposite angle, gaze steadily locks on the camera, phone still raised in place, freezing into a straighter, more curvaceous selfie pose than the opening. Whole movement uses a normal slow speed, hip weight shift must be obvious, not just breathing and blinking; do not suddenly put down the phone, do not swing head widely, do not turn around, do not change clothing or body proportions, keep fingers, arms, and phone structure stable.
