光り輝く水中を進む英雄サメとスチームパンク仲間たち

A hero shark with brass‑plated snout, oversized whimsical goggles, gear‑powered fin attachments, glowing teal eyes, drifting confidently through the midground. Three supporting sharks follow in staggered formation: • one with a tiny propeller backpack • one with a monocle and copper mustache plate • one with a warm lantern‑jaw glow Foreground: curved copper pipes, bubble vents puffing rhythmically, kelp‑like cables swaying. Midground: sharks gliding left‑to‑right with playful bubble trails. Background: whimsical steampunk coral structures, brass domes, rotating gears, soft teal‑gold gradients fading into the deep. A small whimsical copper mini‑submarine drifts behind the sharks in parallax, its polished hull engraved in elegant calligraphy with the signature: Bic Revelation, illuminated by a soft golden glow, tiny rotating gear beside the engraving. Warm brass highlights, gentle shafts of filtered light, drifting particulate, soft cartoon exaggeration while maintaining cinematic polish. Golden‑ratio placement, 20–30% negative space for clean scrolling, dreamy underwater atmosphere, cohesive whimsical steampunk fantasy tone.
