((masterpiece)),((best quality)),((high detial)),((realistic,)), Imagine standing at the edge of a breathtaking waterfall that cascades gracefully within the underground metropolis. The water tumbles down from a rocky overhang, creating a shimmering curtain that reflects the soft glow of bioluminescent plants lining the cavern walls. Below, a serene pool collects the water, its surface glistening like glass, surrounded by smooth stones and vibrant flora. Residents gather nearby, drawn by the soothing sound of rushing water, while children splash playfully at the edges. In the background, towering structures rise, their facades adorned with greenery, creating a stunning contrast against the natural beauty of the waterfall, embodying the perfect blend of nature and urban life.
