PROMPT:
A whimsical, vibrant, and photorealistic comic style cartoon depicting a fantastical underwater metropolis, teeming with life and activity, where majestic, iridescent sea creatures and anthropomorphic aquatic beings go about their daily business, amidst towering, intricately designed coral skyscrapers, grand archways, and winding, luminous kelp avenues, all set against a radiant, electric blue background, with bursts of sunshine illuminating the scene, and accents of emerald green, amber, and turquoise, while minimizing the use of pink hues, capturing the mesmerizing essence of an otherworldly, aquatic society at the peak of its glory.
