Create a highly detailed, hyper-realistic 3D model of a Skull Archfiend of Lightning demon, inspired by the minotaur from Path of Exile and the stylistic influences of American Gods and Reaper Minis. The demon should have chalk white skin, red horns, and be holding an axe. The desired style should be a mix of medieval and dark fantasy, with vibrant colors and dynamic lighting. The model should be rendered in high definition (4K) with a 50mm lens, featuring cinematic lighting, rim light, and realistic water and saturated cloud effects. The background should be a white or light-colored surface with subtle shadows. Please use a golden ratio composition and ensure that the model is posed in a dramatic, dynamic way. Incorporate micro details and lifelike textures to create a highly realistic and immersive scene.
