Encuentro de Jefe Monstruo Abisal

Cinematic AAA game key art of an underwater dark-fantasy boss encounter, using the rough silhouette and color scheme of the reference photo (a front-facing rounded dolphin or whale body, dorsal fin, pectoral fins, deep blue upper body, pale lower mouth area). The creature is rendered as a colossal, realistic sea monster with wet, rough textured skin encrusted with barnacles and grime, cracked glowing [electric blue] markings, bioluminescent eyes, and ornate ancient gold engravings running down its forehead. Setting: A vast [abyssal ruined city] with broken stone arches, submerged pillars, ancient statues, floating particles, ambient bubbles, and schools of small fish. A shadowed shipwreck rests on the left, and a tiny deep-sea diver figure near the lower left emphasizes the monster's immense scale. Composition & Lighting: Centered widescreen composition with the creature looming directly toward the camera. Dramatic volumetric blue light shafts descending from the water surface, moody teal and deep-blue color palette, high contrast, [ominous and epic] atmosphere, with sharp focus on the monster's face. Game UI: Exactly one boss health bar at the bottom center featuring a long crimson gauge inside an ornate dark-metal fantasy frame, labeled with the text "[深渊歌者]". No additional UI elements.
