Create a dark and horrifying digital artwork featuring a demonic nun with twiste

Create a dark and horrifying digital artwork featuring a demonic nun with twisted, black horns protruding from her head. She has pale skin, glowing white eyes, and an open mouth with a long, blood-dripping tongue. Her body is covered in tattoos of skulls and dark symbols. The nun is holding a large, blood-soaked cross with a chained rosary wrapped around it, and a suffering face is embedded in the cross. The background is filled with shadowy figures resembling skeletons or demonic entities, with a foggy and eerie atmosphere.
