The ravenous character face is a detailed, monochromatic drawing by Tsutomu Nihei in a style reminiscent of traditional manga or anime. It depicts a humanoid skull-like face with a smooth, pale, almost white complexion. The skull is devoid of any flesh, revealing a stark, skeletal structure. The eyes are large and round, set deep within the skull, giving a haunting, eerie expression. The mouth is wide open, exposing sharp, jagged teeth, creating a sense of menace. 

Several circular, metallic studs are embedded along the forehead, adding a mechanical or robotic element to the design. The texture of the face is smooth, with fine lines indicating cracks and fissures, enhancing the sense of age and decay. The background is dark, providing stark contrast to the skull, with no discernible details, focusing the viewer's attention solely on the face. 

The drawing style uses cross-hatching techniques to create shading and depth, giving the skull a three-dimensional appearance despite being flat. The overall mood of the image is dark and unsettling, with a strong emphasis on horror and the macabre.
