Create a cinematic image of a majestic water dragon swimming powerfully through the turbulent open ocean during a fierce storm, with a focus on dramatic lighting and intense detail. The dragon's sinuous, serpentine body, measuring at least 50 feet in length, is covered in iridescent scales that shimmer in shades of cobalt blue, turquoise, and silver, mirroring the chaotic, stormy waters. Its eyes glow with an ethereal, electric blue light, casting an unsettling, otherworldly glow against the dark, foreboding sky. The dragon's flowing mane and whiskers appear liquid, blending seamlessly into the crashing ocean waves as if composed of water itself. Towering waves, reaching heights of over 20 feet, surge and crash around the dragon, generating a spray of white foam that fills the air, while sheets of heavy rain pour down from above. The stormy sky above is a deep, foreboding grey, with swirling clouds and flashes of bright, electric lightning that illuminate the scene in stark, dramatic bursts. The ocean's surface is churning violently, emphasizing the raw power of the elements and the formidable presence of the water dragon. Incorporate cinematic details such as mist, spray, and atmospheric effects to enhance the sense of drama and intensity.
