A realistic, close-up fashion portrait of a 25-year-old adult woman with shoulder-length dark auburn hair, walking along a sun-dappled mountain forest trail. She has a vibrant, colorful mountain wildflower tucked behind her ear. She is wearing a simple, casual cotton top and is smiling warmly at the camera. The background features soft-focus towering pine trees and dappled sunlight filtering through the canopy, creating a natural, ethereal glow. The framing is a tight close-up, capturing her face and shoulders, with her hair styled in a natural, slightly tousled way consistent with a day of hiking. The lighting is soft and golden, highlighting the texture of her hair and the delicate petals of the wildflower. The depicted adult woman has shoulder-length dark auburn hair. Show her face clearly toward the camera at a mild three-quarter angle, large enough for a natural portrait face reference.
