High quality 3D portrait rendering of a Ghoul guarding the gates of Hell. A burning spectral aura surrounds a twisted, hellish skull with glowing, ember-red eyes. Its gaunt, elongated frame draped in tattered, ancient rags that whisper of forgotten eras. The scene is alive with vivid, detailed flames and swirling fire casting flickering shadows across the ground, set against a background of molten inferno and churning darkness. Emphasizing dark fantasy horror, the environment is steeped in dramatic, cinematic red lighting reminiscent of a dystopian nightmare, artstation style, with a dreamlike soft-focus lens effect and shallow depth of field, f/2.2. The ghoul's visage remains free from horns, withered features, or any semblance of humanity, evoking a chilling presence that’s both sublime and terrifying.
