Backstage VHS Fashion Portrait

Create a realistic cinematic backstage concert photo of subject kneeling on a dark glossy stage floor, posed in profile with her body arched forward and her forearms resting on a large black touring road case at the left. She looks directly at the camera with a sultry calm expression, long dark wavy hair falling over her shoulder, wearing a tight light gray spaghetti-strap mini dress and metallic silver strappy high-heeled sandals with ankle wraps. The environment is an underground live house or music venue backstage: black curtains, stacked equipment flight cases, cables, a rain-speckled window, drink bottles and cans on top of cases, and a large rear road case labeled “UNDERGROUND LIVE HOUSE LONDON.” Add the number “13” on the front-left case. Use moody low-key club lighting with magenta rim light behind her hair and body, cyan-blue highlights from the window, deep shadows, reflective floor shine, and subtle red/cyan chromatic aberration. Frame as a horizontal 16:9 analog camcorder still, waist-level perspective, subject centered-left, full body visible from head to heels. Add VHS timestamp overlay in the bottom left reading timestamp_text, white blocky digital text with slight glow and scanline artifacts. Style should be photorealistic, editorial fashion, gritty music-video backstage atmosphere, slight film grain, soft lens bloom, high detail, no extra people, no watermark.
