Poseidon Sea God Warrior

Create a dramatic vertical fantasy anime illustration of {argument name="deity character" default="Poseidon, god of the sea"} as a young, handsome sea god warrior standing in a storm of glowing ocean water. He has {argument name="hair color" default="vivid turquoise-blue"} windswept wavy hair, sharp blue eyes, a calm serious expression, and a small ornate gold crown or horn-like diadem. He wears luminous crystalline aqua armor with gold filigree trim, layered shoulder plates, bracers, and a flowing translucent white-and-blue cape that looks like sea foam. In his foreground hand he grips a tall polished golden trident with exactly three long spear prongs, each prong shaped like elegant flame-like blades and glowing with divine light. Behind him, a massive serpentine water dragon made of translucent blue waves coils across the upper background, with an angular dragon head, icy fins, and splashing crystalline scales. The composition is dynamic and heroic, low-angle three-quarter view, the trident rising vertically along the left side, the character centered slightly right, swirling waves forming a circular vortex around him. Use deep navy night-ocean background, cyan bioluminescent highlights, white foam splashes, gold rim lighting, sparkling water droplets, high contrast, ultra-detailed digital painting, polished gacha-game key visual style, cinematic lighting, sharp linework, radiant magical effects, no text, no logo, no watermark.
