Design a 1000-meter residential tower that embodies the essence of Shanghai, blending modern innovation with cultural elegance. The tower should have a fluid, graceful form with curved lines inspired by the flowing movement of the Huangpu River. Use materials like shimmering glass and metal, with tiered sections reminiscent of pagodas but modernized. The design should play with light and shadow for dynamic effects. No background elements, just the tower. --ar 9:16
