Masterpiece, high quality, flat color scheme, limited palette, subtle contrast, featuring one girl with long, sleek black hair, surrounded by a halo. She is wearing a backpack, gazing into the distance while standing. The scene includes wisps of smoke against a backdrop of a nighttime city, with a sunset casting warm tones. Skyscrapers rise amidst a landscape of bridges and road signs, creating a sense of depth. A palette of black, deep red, burnt orange, and rich brown evokes the essence of autumn, mingling with a soft haze.
