Cinematic Rainbow Prism Portrait Prompt

[Higgsfield Soul 2.0 Prompt] ar 9:16 2K A close-up cinematic portrait of a young woman with pale porcelain skin and long, dark, slightly damp, messy hair falling across her face in loose strands. She has intense amber-hazel eyes, one partially veiled by hair, a soft yet piercing gaze directed at the viewer, and slightly parted glossy lips. A vivid diagonal rainbow prism / light-refraction beam cuts across her face from the forehead down over one eye, cheek, and onto her bare shoulder, showing clear spectral colors (red, orange, yellow, green, cyan, blue, violet). The left side of her face is in deep shadow while the rainbow-lit side glows. Dark, almost black background, high contrast, dramatic rim and volumetric lighting, painterly digital art style with smooth skin rendering, fine hair detail, and a moody, ethereal atmosphere. Vertical composition, photorealistic-yet-stylized, ultra-detailed.
