A hyper-realistic full-body sculpture of an ancient demonic female Angel, named Rucifer, combining gothic and baroque elements, stands in a grand gothic cathedral. She wears an intricately detailed long veiled dress and possesses six elongated wings. Her shadowy halo casts a mysterious aura. The scene is cinematic, featuring Guillermo del Toro's imaginative style, captured with epic perspective and low contrast detail. The sculpture, meticulously crafted with bone-like textures, is rendered using Zbrush and Octane, illuminated by volumetric light, with Earth visible from behind, creating a dark, epic atmosphere. The composition adheres to the rule of thirds, utilizing Unreal Engine 5 for a stunning photorealistic 8k outcome, showcasing ultra-detailed technical precision in a hauntingly beautiful setting.
