Abyssal Ruined City Sea Monster Boss Encounter AI Image Prompt

Using the provided reference image as the rough silhouette and color guide, transform the simple blue dolphin sketch into a cinematic dark-fantasy underwater boss encounter. Keep the same front-facing rounded dolphin/whale-like body, central dorsal fin, side fins, blue upper body, and pale lower mouth area, but render it as a massive realistic sea monster with cracked glowing electric-blue markings, bioluminescent blue eyes, wet rough skin, barnacles, grime, and ornate ancient-gold markings running down the forehead. Scene: Place the creature in a vast abyssal ruined city with dramatic blue shafts of light from above, floating debris, bubbles, schools of tiny fish, broken stone arches, pillars, statues, and a ruined shipwreck silhouette on the left. Add a tiny explorer/diver figure near the lower left to emphasize the monster's enormous scale. Make the composition widescreen and centered, with the monster looming directly toward the viewer. Game UI addition: Add exactly 1 boss health bar at the bottom center: a long red bar in an ornate dark-metal fantasy frame, labeled in Chinese with {argument name="boss name" default="深渊歌者"}. Do not add any other UI panels. Style: Ultra-detailed AAA game key art, dark souls-like fantasy atmosphere, underwater volumetric lighting, high contrast, moody teal-blue palette, cinematic realism, dramatic scale, sharp focus on the creature's face. Customizable details: creature glow color {argument name="glow color" default="electric blue"}, environment theme {argument name="environment theme" default="abyssal ruined city"}, mood {argument name="mood" default="ominous and epic"}, aspect ratio {argument name="aspect ratio" default="16:9 widescreen"}.
