Urban Mirror Selfie with Dynamic Background Motion Blur

A mirror selfie of a young woman with the subject in sharp focus while the background shows horizontal motion blur, as if people or surroundings are moving behind her. She holds a phone in front of her face, wearing a black top and leather jacket. The blur appears only in the background, creating a sense of movement, while the subject remains crisp and clear. Lighting is indoor and balanced, colors are neutral. Cinematic motion blur effect, sharp subject isolation, modern urban aesthetic, no artificial face smoothing, dynamic lifestyle photo.
