Portrait composition, a small lantern floating inside a vast dark ocean cavern, its warm amber light enclosed by a translucent shell of layered glass and salt-crusted crystal; outside, immense soft shadows press close but never touch it. A single human hand, indistinct and made of mist, rests nearby without grasping. Deep midnight blue, charcoal, and gold, quiet tension softened by tenderness, surreal painterly realism, cinematic low light, fine luminous particles drifting through the water, no text, no symbols, vertical frame.
