Romantic Winter Couple in a Snowy Mountain Cabin | Cozy 4K Portrait

Create an ultra-realistic 4K winter fashion portrait of a beautiful young couple standing closely together outside a luxurious rustic mountain cabin surrounded by fresh snow. The woman has long, voluminous, wavy dark brown hair with subtle caramel highlights, expressive brown eyes, naturally rosy cheeks, soft pink lips, and a warm, confident smile. She wears a cozy oversized black ribbed turtleneck sweater with long sleeves and fitted black trousers, paired with elegant gold hoop earrings. One hand gently touches her hair while the other rests casually in her pocket. Beside her stands a handsome young man with thick, naturally curly dark brown hair, well-defined facial features, expressive eyes, and a gentle smile. He wears a sophisticated charcoal-gray wool overcoat layered over an ivory cable-knit sweater, paired with tailored black trousers. He stands close to the woman with one arm resting naturally around her shoulders, creating a warm and romantic couple pose. The background features a beautiful wooden alpine cabin with rustic stone walls, large windows glowing with warm golden light, vintage outdoor lanterns, snow-covered wooden railings, frosted evergreen trees, and distant mountains covered in white snow. Soft winter daylight illuminates their faces, while the warm cabin lighting creates a cinematic contrast between cool snowy surroundings and cozy golden tones. Use professional fashion photography, realistic skin texture, detailed knitted fabrics, natural hair strands, accurate anatomy, realistic hands, soft shadows, shallow depth of field, balanced exposure, and premium cinematic color grading. Capture the couple in a vertical three-quarter portrait with both faces sharply focused and the snowy mountain scenery softly blurred behind them.
