Portrait Studio Cinématographique d'une Fille Confiante en Bleu Canard

A cinematic, studio-lit portrait of a confident young girl sitting on a modern teal armchair. She is wearing a teal turtleneck, matching teal pants, a black blazer, and black loafers. She has long, wavy dark brown hair with a thin headband. She is wearing black rectangular sunglasses, giving a powerful and stylish expression. Her posture is relaxed yet authoritative: legs crossed, one arm resting on the armrest holding a thin paintbrush, the other hand relaxed. Subtle teal paint marks are visible on her fingers. Behind her, a symmetrical curved wall features multiple vertical illuminated panels, each displaying slightly different angles and expressions of the same girl wearing sunglasses, creating a multi-perspective reflection effect. The background lighting is warm, soft beige tones with glowing panel edges, giving a premium, futuristic gallery feel. The composition is perfectly centered, highly detailed, ultra-realistic, sharp focus, soft shadows, cinematic lighting, 8k resolution, fashion editorial style, luxury aesthetic, depth of field, clean studio environment.
