A highly realistic medieval knight with short black wavy hair and slightly downturned eyes, wearing intricately detailed but authentic armor. The armor features a mix of polished steel and darkened accents, with realistic textures like wear and scratches. The knight’s helmet is designed with subtle, practical details, and the overall appearance should convey both strength and historical accuracy. The background is a natural, muted setting, like a stone courtyard or a battlefield, to highlight the knight’s realistic armor and features.
