Fortress Gladiator Concept Art in Stone Citadel

Ultra-detailed concept art of a lone gladiator standing in a dim, imposing fortress courtyard. Bronze lorica segmentata armor with leather skirt, a crimson-plumed crested helmet, a shield under one arm, and a gladius at his side. Weathered stone walls, cracked marble, torches flaring along battlements, banners torn by wind. Dust and sunbeams piercing smoky air create dramatic chiaroscuro. Dynamic low-angle perspective emphasizing the fortress's scale, cinematic lighting, rich textures, wet stone reflections, and a painterly digital-art style suited for high fantasy concept art.
