High quality 3D portrait rendering of a spectral Ghoul standing vigil at the gates of Hell. Its head is a burning infernal skull with glowing ember-like eyes. With a tall, slender body and an intricately detailed skeleton shrouded in tattered, ancient robes, the scene captures a chilling elegance. Surrounding it, vibrant flames and scorching fire dominate the background in a display of dark fantasy horror. The atmosphere is steeped in dramatic and cinematic red lighting reminiscent of a fantasy realm, lending an eerily beautiful glow to the entire composition. The ghoul casts a foreboding presence, amplified by a soft-focus depth of field, creating an ethereal yet sinister allure.
