Realistic AI Portrait of Girl with Acoustic Guitar

Create an ultra-realistic 9:16 vertical portrait of a young South Asian woman sitting casually with a natural-finish acoustic guitar across her lap. She is wearing a loose-fitting black button-up shirt with a soft, slightly faded texture, a relaxed collar, and sleeves casually rolled up to her elbows, paired with dark charcoal-grey washed jeans. She accessorizes with a delicate silver chain necklace and a thin silver bracelet. Her long, thick, dark-brown hair is styled in voluminous, feathered layers with face-framing curtain bangs and flipped-out ends, cascading over her shoulders and chest. She gently plays the guitar, with one hand positioned near the sound hole and the other holding the fretboard. Her head is slightly turned to the side, eyes looking down toward the guitar, with a subtle, natural smile and soft pink lips. She sits in a relaxed pose against a plain beige indoor wall. Warm ambient lighting, cozy aesthetic, soft shadows, cinematic golden tones, shallow depth of field, natural skin texture, realistic hair strands, subtle film grain, candid Instagram photography, DSLR quality, highly detailed and photorealistic.
