Ultra-realistic photography, 9:16 vertical smartphone wallpaper. A mysterious young man with shoulder-length dirty blond hair, light stubble, and rugged appearance sitting on a black outlaw-style cruiser motorcycle. He is making a "shhh" silencing gesture with his index finger over his lips, looking intensely and directly at the viewer. His face is partially concealed by dramatic shadows, creating an enigmatic presence. He wears a black leather biker vest over a dark shirt, rugged jeans, and biker boots. Environment: Empty road at night, subtle fog, soft floating particles, distant city lights, dramatic cinematic lighting. Color palette: Black, dark gray, muted blue tones. High contrast, shallow depth of field, highly detailed skin and leather textures, 4K resolution, sophisticated and introspective atmosphere. Text overlay at bottom-right corner: "DON'T ALWAYS SAY WHAT'S ON YOUR MIND" in clean cinematic white subtitle font, small, readable, with subtle shadowing. --ar 9:16 --style raw --v 6.0
