Cinematic Staircase Portrait

Hyper-realistic IMAX-level Netflix-style cinematic portrait, 9:16 vertical. Use the uploaded image as the primary visual reference and preserve the exact facial identity, proportions, and defining features. A woman sits curled up on a rustic wooden staircase, framed by dark, weathered timber beams. Her knees are bent and drawn close together in front of her body, with her thighs angled toward the camera. One hand rests loosely across the top of her raised knee, fingers naturally curved over the kneecap, while her other hand reaches down alongside her leg, gently resting near the opposite shin. Her torso is slightly turned to the side, with one shoulder exposed as an oversized brown, charcoal, and muted beige plaid flannel shirt slips casually off it. Beneath the open flannel, she wears a simple fitted black camisole, paired with dark shorts that are mostly concealed by her seated pose. Her head is turned gently toward her exposed shoulder, chin lowered, eyes softly closed or cast downward, creating a quiet, introspective expression. Her lips are naturally closed with a soft, relaxed pout, and her facial muscles remain gentle and unposed, giving her a serene, thoughtful, slightly wistful appearance. Her dark brown, nearly black hair is styled in a tousled, shoulder-length layered shag with wispy curtain bangs, softly framing her cheeks and forehead, with loose, slightly wavy strands falling around her jaw and neck. Fair luminous porcelain skin with a bright ivory to light beige tone and a neutral-cool undertone, with natural realistic skin texture and soft highlights, subtly warmed by the ambient golden light. The setting is an intimate, rustic wooden interior with deep brown timber framing, shadowy stair treads, and a softly blurred background. Warm amber light enters from the side, delicately illuminating her face, hair, and bare shoulder while leaving the surrounding wood in rich, cinematic shadows. Apply a moody, warm vintage color grade with earthy sepia-brown tones, muted highlights, deep chocolate shadows, and soft golden rim lighting. Preserve realistic skin tones, detailed plaid fabric texture, and a natural film-like atmosphere.
