Gothic Catgirl Cosplay Dressing Room

Create a cinematic photorealistic cosplay dressing-room portrait of a young woman wearing a dark gothic catgirl idol costume in black and purple. She stands turned away in a three-quarter back pose, looking over her shoulder toward the camera, with long wavy {argument name="hair color" default="black"} hair, black cat ears, large black over-ear headphones, purple satin bows, dangling chain accessories, sheer black detached sleeves, a purple corset-style back with black crisscross lacing, and a short layered ruffled skirt. Her face is intentionally obscured by a flat rectangular brown privacy block. Include exactly one additional reflected figure in the vanity mirror on the left, also wearing the same outfit and with the reflected face obscured by a smaller brown rectangle, plus one large anime poster on the far left wall with its face area obscured by a brown rectangle. Set the scene in a cluttered backstage bedroom vanity area with a mirror, makeup bottles, perfume, small boxes, a black makeup case, clothing rack with dark costumes, and soft wardrobe shelves in the background. Use warm pink-purple evening light, a bright window glow on the right, shallow depth of field, realistic skin highlights, soft lens flare, moody low-contrast shadows, and a high-end DSLR photography look. The dominant palette should be {argument name="color palette" default="black, lavender purple, dusty rose, and warm amber"}. Keep the composition horizontal 3:2, subject on the right third, mirror and vanity on the left, no readable text, no watermark.
