Siren in a Robotic Factory: Photorealistic Ambience

Photorealistic render of a siren standing in a sprawling robot factory at twilight. The siren is humanoid with subtle aquatic features: pale cyan skin with delicate iridescent scales along the shoulders and forearms, faint gill slits, and webbed like fins behind the ears. Her long wet hair clings to her neck and shoulders. She stands on a wet metal catwalk above a tangle of conveyors, robotic arms, and CNC machines. Cold blue and teal factory lighting contrasts with warm orange welding sparks; steam and rainlike droplets cling to surfaces. The environment is filled with chrome, pipes, and machinery. The siren raises a calm but commanding gaze as if singing, though no sound is depicted. Cinematic composition with a slight low angle perspective and shallow depth of field. Hyper realistic textures including glistening skin and scales, wet hair, oil slicks on metal, micro scratches, and subtle bioluminescent glow from her scales. The mood is eerie yet awe inspiring, blending myth with industry in photorealistic style.
