Create an abstract landscape that combines elements of nature and urban life. The image should feature a vibrant mix of colors, including deep blues, rich greens, and warm orange tones. Blend soft, organic shapes resembling mountains and forests with sharp, geometric lines representing city skyscrapers and bridges. The sky should have a dramatic sunset with radiant, swirling clouds. The overall mood should evoke harmony between nature and human architecture, with contrasting textures like rough stone and sleek metal, while maintaining an ethereal, dreamlike atmosphere.
