a 16K ultra-high-definition vector art of a striking, exotic nun assassin who specializes in vampire hunting. Place her in a dark, gothic park under a moonlit sky, with mist swirling around ancient tombstones and iron-wrought crosses. She should have a fierce yet serene expression, wearing a tactical, modified nun’s attire—blending traditional robes with leather armor, silver stakes, and a weapon belt. Add subtle, mystical elements like holy symbols and a faint glow on her weapons, hinting at her vampire-hunting skills. Capture a dark, cinematic atmosphere with film grain, sharp focus, and realistic textures, ensuring a perfectly balanced, immersive scene without extreme angles or exaggerated expressions. Apply anti-glare effects and all necessary enhancements for an award-quality illustration.
