The second step in a multi-step process, this prompt generates a high-resolution (4K recommended) image of a gigantic abstract enemy entity, described as being formed entirely from swirling black mist with a traditional Noh mask face, set against a dark, mountainous landscape.
A gigantic abstract entity formed entirely from swirling black mist,
its body loosely humanoid but constantly shifting,
a large traditional Noh mask emerging from the fog as its face,
no solid body, only dense smoke shaping arms and torso,
black mist flowing and dissolving into the surrounding air,
dark mountainous landscape beneath,
soft diffused moonlight cutting through the fog,
highly cinematic realism, symbolic and minimal,
film still, subdued color palette, 35mm lens look
