A masked mystical samurai fiercely engaging enemies with his enchanted katana in a grim battle. His armor is star-dusted and full-bodied, emitting plumes of jet-black smoke. The epic landscape features detailed, atmospheric elements from the Sengoku period, evoking a dark and morbid renaissance vibe. Volumetric light cuts through the battlefield filled with winter's chill and crimson red puddles. The style mirrors the intricate, highly realistic work of Greg Rutkowski and Marc Simonetti, rendered as an ultra-wide, epic shot in digital art, utilizing Unreal Engine 5 for an award-winning piece. The scene captures a gritty yet fantastical clash amid a frozen, war-torn landscape.
