"Sewer Chimera" - Scene design

Something lurks in the depths... something big and dangerous waits in the dark...
Darkness, filth, mysticism, and terror attacking at high speed. These were the main thoughts in my head during the creation of this illustration. The main challenge was how to arrange the details within the image, so that everything is rich in detail and interpretable, but at the same time the mysticism and mystery of the image remains. To give a complete picture by showing as little as possible (keeping this criterion in mind from the first moments of the works, so as not to cause myself unnecessary work, jumping back and forth between processes)
