Knight in the Stadium: Concept Art Showdown

Ultra-detailed concept art of a lone knight in gleaming plate armor standing center stage in a vast stadium at dusk. Blue and gold floodlights carve reflections on polished armor; holographic banners ripple overhead. The knight holds a sword point-down in one hand and a shield with a heraldic crest in the other; cape billows behind. Weathered textures on cuirass and gauntlets, chainmail visible at joints. The arena floor is etched with ancient runes; the stands are filled with a blurred roaring crowd, steel rails and polished concrete surrounding the field. Painterly, cinematic lighting, dynamic composition, depth of field, dust motes, and subtle lens flares. Fantasy-meets-sci-fi concept art vibe for a dramatic hero moment.
