Amajestic mermaid taking a selfie with a massive, god-like mako shark with razor-sharp teeth and piercing yellow eyes, both silhouetted against a breathtaking, sun-drenched tropical horizon with coral reefs and crystal-clear waters, the shark's grotesquely disfigured body glinting with chromed metal implants and vibrant blue accents, as the mermaid smiles brightly with a flawless, genetically-engineered complexion and neon blue highlights, with an artistic focus on precision textures and physiological details in 8k, cinematic lighting effects, and a NFixer filter that enhances the NRealFixer preset to emphasize the surreal, underwater story in.75 polarized mode.
