Medieval knight in the studio

{
  "prompt": "Place a man (use the provided image for accurate facial features), as a fully armored, helmetless knight in medieval armor of dark steel plate with lighter metal accents, stands in a ready pose. He wears armor, a dark red tunic with long sleeves and a skirt reaching to the knees, over chainmail. A dark belt with a silver buckle cinches the tunic at the waist. A black cloak drapes elegantly over his left shoulder. In his left hand, he holds a longsword, the silver blade reflecting the light and the hilt dark. His right hand is clenched into a fist. The background is a solid, smooth gray, with no distractions. The lighting is even, highlighting the details of the armor."
