That's what makes a great skyline: it's more than the sum of its parts. You could have the same buildings, but not arranged so perfectly, and it would not be as great of a skyline. Not as many skyscrapers as New York, but spaced perfectly to form a whole, and still be admired individually (although like New York, there are many beautiful buildings that are crowded out and can't be appreciated unless you're right across the street).
