Prompt

A young woman sitting in the driver's seat of a luxury car, holding a black polka-dot phone case with a cute cat decoration. She gently shakes and rotates the phone in her hand to show off the newly purchased case. Small wrist movements, slowly tilting left and right, then slightly rotating the phone forward and backward to catch the light on the texture and camera area. Natural hand motion, subtle finger adjustments, proud and satisfied feeling. The phone remains the main focus at all times. Background stays stable inside the luxury car interior with soft daylight. Shallow depth of field, realistic motion, handheld smartphone commercial style, smooth camera, ultra realistic, 4K, no scene changes, no extra actions, no talking.
