Thank You! I love supertall towers in big cities, like a number of them that are going up in New York City right now. 432 Park Avenue was topped-off at 1,396 feet, a hundred feet taller than the Empire State building. It's a super-thin shaft which has forever changed the appearance of Midtown New York from a distance. More are coming! My skyscrapers sometimes contain gothic elements, and look more like the 1913 Woolworth Building, in Lower Manhattan.
