Turn him into a heroic medieval warrior standing on a snowy battlefield in a dark fantasy world, inspired by Game of Thrones. Long dark leather armor with metal plates, fur around the neck, a sword in one hand, cape blowing in the cold wind, snowflakes in the air, stormy grey sky, distant army silhouettes and ruined castle in the background, cinematic wide‑angle shot, slightly low camera angle to make him look powerful, ultra‑realistic lighting, cold blue and silver tones with a touch of warm fire glow from burning wreckage behind, 8K ultra‑detailed, highly detailed clothing textures, realistic snow on armor and hair, dramatic atmosphere.
