Prompt: An underwater snowscape at dusk, with the last rays of the sun piercing the water's surface, casting a warm glow on the snowflakes gently settling on the sandy ocean floor. In the foreground, a group of mermaids in festive attire, their scales shimmering in the fading light, exchange gifts wrapped in seaweed ribbons. Schools of angelfish, their bodies adorned with tiny reindeer antlers, dart through the snowflake-filled waters, creating a festive atmosphere.
