Prompt: A close-up portrait of King Arthur, in full armor and flowing royal cape, sitting confidently astride his mighty war steed, gazing out across a misty medieval battlefield at dawn. Stylized in the epic, cinematic style of ArtStation concept artists like Baranko Markovic, Sebastian Högberg, and Jinha Lee. Intricate armor details, soft morning light accentuating Arthur's determined expression and noble features. Animated magic particles emanate from Arthur's legendary sword Excalibur which rests at his side. Ambient occlusion, volumetric lighting, dramatic depth of field. Regal, dignified, ready to lead his knights into glorious battle. Digital painting, hyper realistic, beautiful and striking.
