"Generate a bird's-eye view illustration of a modern apartment building in the urban center of Seoul. The design should prominently feature curtain walls that emphasize verticality, while also incorporating horizontal elements such as balconies or terraces that create a harmonious balance. The surrounding area should reflect the low-rise residential neighborhoods typical of Seoul, showcasing a blend of contemporary and traditional architectural styles. The color scheme should be modern and elegant, focusing on neutral tones and glass reflections."
