A 3D model of the Night King would likely feature his distinctive appearance: icy blue skin, glowing blue eyes, and a crown-like arrangement of horns on his head. The model might depict him in his menacing armor, adorned with intricate ice-like patterns and textures. His facial features, including his sharp cheekbones and stern expression, would be captured to convey his imposing presence. Additionally, the model might include subtle details like frosty breath or shimmering aura to enhance the supernatural aspect of the character.
