A hyper-realistic sculptural depiction of a demonic female angel named Rucifer stands in the center of a grand gothic cathedral. This intricate and ornate baroque masterpiece showcases her wearing a long, flowing veil dress, with six expansive wings unfurled behind her. A shadowy halo hovers above her head, suggesting her fallen status. The scene is bathed in soft, volumetric light that seeps through the stained glass windows, creating a cinematic atmosphere of both awe and trepidation. The perspective is epic, detailed with ultra-precision, capturing the subtle textures of bone and fabric as if rendered in ZBrush with the highest fidelity. The ambient lighting complements the composition, emphasizing the rule of thirds in a photorealistic manner, as if rendered with Unreal Engine 5 in 8k. The earth looms in the background, partially illuminated, casting an otherworldly glow over the sculpture that blends Guillermo del Toro's imaginative style with a dark, epic realism.
