AI Prompt for Vintage-Style Flashlit Profile Portraits

"A close-up candid portrait of a {argument name="subject" default="young woman"} indoors against a muted beige wall, shot in a 1990s disposable camera snapshot style. She has pale skin, a soft understated smirk, and loose {argument name="hair color" default="black"} hair with natural volume, slightly messy waves, and face-framing strands spreading around her shoulders. She wears a {argument name="top color" default="faded mauve"} oversized sweatshirt with a relaxed fit and softly gathered sleeves. The framing is chest-up and slightly off-center at eye level, with her body angled casually and one arm subtly extending forward as if taking the photo herself. Use direct on-camera flash for flat shadows, a dim ambient room, visible but subtle film grain, soft edge falloff, and a nostalgic casual vibe. The wall behind her is decorated with exactly 8 taped paper items: 4 instant photos, 2 concert flyers, 1 handwritten note, and 1 small dark photo print. One flyer references {argument name="band name" default="SONIC YOUTH"}, another references {argument name="second band name" default="NIRVANA"}. The overall image should feel intimate, imperfect, slightly grainy, and authentically analog."
