Photorealistic half-submerged portrait of a siren surfacing from black brackish water, translucent bioluminescent skin with visible subdermal veins glowing faint cyan, gills flaring along the neck with wet membrane detail, barnacle and coral growths encrusting one shoulder, hair like wet kelp strands plastered across a gaunt face, eyes solid obsidian black with a faint specular highlight, water droplets and rivulets caught mid-drip in freeze-frame clarity, shot with Sony A7R IV, 100mm macro lens, f/2.8, underwater strobe lighting mixed with cold moonlight from above, high dynamic range capturing both shadow detail in the water and highlight detail on wet skin, cinematic teal-and-orange grade, hyperrealistic skin subsurface scattering.
