cinematic conceptual illustration, dramatic volumetric light, painterly, symbolic and evocative, matte finish. A colossal, ancient whale skeleton rests on a dark abyssal plain, its ribs forming a cathedral-like nave. Within its hollow chest, a swirling constellation of bioluminescent jellyfish and tiny glowing fish drift like living stars, casting pale blue and gold light through the bone arches. Deep teal and black water, with scattered sediment motes catching the glow, composition centered, low-angle view upward, mood of sacred wonder and deep time.
