A high-quality 3D portrait rendering of a ghoul standing vigilant at the gates of Hell. The ghoul features a blazing infernal skull with glowing crimson eyes that pierce through the shadows. It has a tall and slender form, with its intricately detailed skeletal structure draped in tattered, ancient rags. The backdrop is an intense display of detailed flames and fiery elements, capturing a dark fantasy horror atmosphere. Dramatic and cinematic red lighting casts eerie shadows, reminiscent of artwork found on platforms like ArtStation, with a soft-focus effect for added depth. The scene is captured with a field of depth (FOD) at f/2.2, adding a sense of realism and intensity. The composition excludes horns, eyes on the body, and any facial features like a nose or hair, focusing purely on the ghoul's haunting presence and the fiery underworld setting.
