Ultra-realistic outdoor portrait selfie of a beautiful young woman

Ultra-realistic outdoor portrait selfie of a beautiful young woman standing beside a crystal-clear mountain stream in a breathtaking alpine landscape. She has long, silky dark brown hair with natural volume, swept gently to one side and cascading over her shoulder. Her face is softly angled toward the camera with a subtle, confident smile, delicate facial features, expressive dark almond-shaped eyes, naturally defined eyebrows, a small refined nose, and soft pink lips. Natural luminous skin with realistic texture and subtle warmth, minimal elegant makeup, and a small beauty mark on her cheek.

She is wearing a fitted ribbed gray-beige sleeveless tank top with thin straps. One arm extends toward the camera as she takes a casual smartphone selfie, while her other hand rests naturally on a rock beside the flowing stream. Relaxed, authentic travel-photography pose.

Behind her is a stunning rugged mountain valley with rocky peaks, green alpine vegetation, a gently flowing river with visible ripples and stones, and a clear bright blue sky. Warm golden sunlight softly illuminates the mountain peaks and her face, creating natural highlights and realistic shadows.
