A hyper-realistic cinematic portrait close-up of a flawless mermaid Sovereign. Her eyes are a striking direct gaze, ga: deep cobalt blue. Her skin is translucent with perfect subsurface scattering, adorned with complex, intricate filigree of polished copper wire, flawless multi-sized pearls, and segments of real dried staghorn coral. Her hair is a rich auburn-red, flowing in wet-pressed waves, integrated with tiny gold flakes and small sea-glass pebbles. Intense sunlight filters through the water creating sharp dancing caustic patterns across her face. Highly detailed scales with turquoise and gold iridescent foil textures covering her neck and shoulders. Deep cobalt and aquamarine water background with high-end macro photography depth of field, f/1.8, 8k resolution. Masterwork by Nano Banana 2.
