Candid autumn selfie with windblown hair and warm golden light

Create a highly realistic, grainy smartphone selfie captured without showing the camera. She tilts her head slightly while her sleek, straight hair falls naturally across part of her face, with several strands caught in the wind and showing subtle motion blur as they reflect the warm sunlight. She wears a black turtleneck layered with a soft gray poncho and delicate sunglasses featuring a thin gold frame. Her lips form a closed, subtle smile, giving her a playful and subtly alluring expression. Behind her is a beautiful autumn landscape beneath a clear blue sky, with low golden sunlight creating soft, warm highlights across her face and hair. The image should feel like an authentic compressed smartphone photo or a casual story screenshot—natural skin texture, gentle grain, soft contrast, slightly imperfect and candid rather than overly polished.
