Nighttime beach fairy wand snapshot

Create a candid nighttime beach flash photo, with a person as the main subject.{argument name="subject" default="young women"} She crouched barefoot on the damp sand, wearing a short white spaghetti-strap summer dress with pink floral patterns. Her left hand held a lit sparkler near the sand, creating a bright golden halo and star-shaped sparks that illuminated her hands and the lower left foreground. Her right hand was near her toes, her knees were bent, and her body was in a three-quarter profile facing the camera. Her medium-length hair {argument name="hair color" default="brown"} The hair is disheveled, slightly windblown. The face is completely obscured by a centered, pure beige rectangular blur/mask, revealing no facial details. The background is a dark nighttime ocean with small waves lapping in, the wet sand reflecting the warm glow of streetlights, and a long, blurred, yellowish-white promenade of lights stretching into the distance along the shore. The design employs a grainy, imperfect film camera aesthetic, using direct flash, high ISO noise, slight motion blur, warm highlights, a deep blue-black sky, and a vertical handheld composition. There is no text, no watermark, no extraneous figures; only a sparkler, a crouching subject, and a single beige rectangle obscuring the face are visible.
