"Create a highly detailed, lifelike digital painting of a Headless Knight on a Freezing Point, with infinity blade armor and Black Rose Dragon features, inspired by DND and concept art from artists like Artgerm, Greg Rutkowski, and Alphonse Mucha. Incorporate anatomic details, a black shirt underneath the armor, and a blacksmith in the background. The style should resemble a smooth and sharp illustration, rendered with Octane or Unreal Engine, and showcasing a grainy, muted color palette, aiming for the golden ratio in composition. Desired output is HD, suitable for Artstation and a cinematic reveal, with a space camera footage feel. "
