Shot in a gritty, high-contrast, cinematic style with a shallow depth of field and warm, golden hour lighting, a closeup of a battle-worn knight's helmet, crafted from ancient, yellowed bones, with intricate, macabre carvings of skulls and serpents, and a crimson, tattered hood, torn and frayed, with threads of crimson fabric clinging to the bone armor's surface, set against a backdrop of ominous, dark clouds, with flashes of lightning illuminating the turbulent sky, amidst a faint, eerie glow of luminescent mushrooms growing on the bone armor's surface, surrounded by tangled, thorny vines and twisted, gnarled tree branches, with a subtle, warm glow of embers or torches flickering in the distance, casting long, ominous shadows across the knight's battered, blood-stained bone armor, with hints of worn, cracked leather straps and weathered, ancient wood, and a few, stray, crimson threads or tassels clinging to the hood's torn edges, amidst a faint, eerie atmosphere of foreboding and decay, with a hint of misty breath escaping from the unseen face, and a few, faint, glowing runes etched into the bone armor's surface, pulsing with a faint, malevolent energy.
