Brutal warrior with a sinister grin, wearing detailed armor and wielding a complex weapon, set against a dark-toned battlefield. Strikes a militant pose in a portrait-style scene with epic composition and dramatic shadows. Fitting the ArtStation trend, designed for wallpaper, using 3D render techniques like Octane and cinematic lighting. Isometric view, crafted in Blender, presented in 8k resolution for a visually stunning and immersive experience, avoiding closeup portraits.
