Density is also an essential trait (again). I find skylines whose skyscrapers are densely packed look better and more impressive than towers scattered here and there at intervals.

It's also significant to have boulevards walled by high-rises, which is spectacular. This is not directly related to a skyline proper, but it obviously affects the look of it, making it denser.

The only benefit of building towers that would be remote from one another is views, but that tends to feed NIMBYism. People protect their views, which is abusive when they don't own what's around their properties. Views are nothing that you could ever regard as private properties, and they're completely insignificant, if not harmful from an urban planning standpoint.

Now the problem with density, for there's got to be at least one, is natural light is almost like luxury when an urban fabric is really dense. That is the case in Manhattan and in Central Paris, for instance. You're often suck in the shadows of buildings and façades all around in these dense cities.
