A high-quality 3D portrait rendering of a Ghoul standing as the guardian of the infernal gates. Its fiery hollow skull emits a sinister glow with intense, glimmering red orbs for eyes. The ghoul possesses a tall and slender frame, its intricately detailed skeleton partially obscured by tattered, ancient rags that flutter in the searing heat. In the background, vivid flames and roaring fire illuminate the scene, casting a dark fantasy horror aura with a dramatic red and cinematic lighting. The environment is captured with soft-focus using a bright aperture, enhancing the ghoul's ominous presence. The skeletal countenance remains eerily devoid of horns, nose, and hair, creating a supernatural atmosphere befitting the gates of Hell.
