Preserve key visual traits such as facial structure and overall proportions, while allowing small natural variations typical of real photography.

A hyper-realistic, ultra-sharp photograph taken on a modern smartphone, specifically an iPhone 15 Pro, characterized by its digital clarity, shot on a modern high-end smartphone camera using a wide-angle lens at ISO 50 and f/1.8. The subject is a young woman in her early 20s, captured in a candid, mid-moment sitting pose on a dark urban surface. She is positioned with her legs spread in a wide, relaxed "V" shape, with her torso angled roughly 15 degrees backward and her head tilted slightly to the left. Her right arm is extended downward, resting her hand on her leg while loosely holding the strap of a leopard-print heel, while her left arm is bent at a sharp 45-degree angle with her hand raised to her face, index finger resting against her lower lip. Her hairstyle features ultra-sleek "glass hair" that is long, dark, and straight, mostly tucked under a beige cotton bandana printed with a black ornate snake pattern. Her expression is poised yet playful, showing a base emotion of fierce confidence with a subtle, candid micro-smirk; her gaze is smoldering and directed at the lens, with the right eye slightly more squinted than the left, creating a glistening inner-corner shine. Her makeup is a "Y2K-glam" style, featuring high-shine glossy nude lips, sharp winged black eyeliner, and shimmering champagne eyeshadow. Her skin displays a healthy radiance with visible pores and a dewy glass-skin finish. She wears a form-fitting ribbed cotton halter-neck tank top with an American flag motif, featuring red and white stripes on the left and a blue field with white stars on the right, paired with high-waisted, medium-wash blue denim jeans showing heavy-duty orange contrast stitching. Accessories include oversized sculptural silver flower earrings and a large silver statement ring. The scene is illuminated by bright, diffused front-facing lighting that mimics a smartphone flash, creating gentle shadows under the jawline. The entire scene is rendered in incredibly sharp focus, from the crisp denim texture to the vertical glowing white neon light tubes in the background, set against a deep indigo twilight sky, devoid of any background blur or film grain, emphasizing a clean digital texture.
