Nano Banana Prompt for a Bold Cinematic Fashion Girl Portrait

@Create image A vertical fashion portrait of a young woman with sleek slicked-back dark hair, wearing pink-tinted aviator sunglasses and large silver hoop earrings, chin tilted up with a confident, aloof expression. She holds a smartphone up near her face in one hand, wearing an oversized beige/cream two-piece loungewear set (relaxed blazer-style jacket and matching wide trousers) over a fitted black turtleneck, layered gold chain necklace. She sits in a relaxed cross-legged pose. The background is a bold gradient sunset of deep orange fading into hot pink and purple, with a large soft-focus glowing yellow circular sun/moon shape positioned directly behind her head like a halo. Dramatic colored rim lighting in blue and purple wraps around her silhouette and clothing, high-contrast studio lighting, vibrant saturated color grading, bold editorial fashion photography style, sharp focus on face and phone, smooth glowing gradient background.
