Create a full-body heroic armored knight standing upright in a neutral pose, arms slightly apart and hands fully visible. The knight wears polished silver armor with gold or white accents—chestplate, pauldrons, gauntlets, and greaves all styled with smooth, noble shapes. A light fabric tabard or waistcloth is attached. The helmet is off or has a clean open-face design. No weapons or dark tones. No overlapping parts. Use a bright fantasy palette and clean neutral background.
