It's not just art style, but it's content style, and simply the theme and overall concept of the server. Even then, the levels aren't the only thing pertaining to art style. There's also hats and the menu screen, and many others as well. Hell, even the sound effects and background music have style. In the end, all of this creates a certain level of unity. In art, unity is valuable, and can make all the difference. If you view video game development as an art, all of what I just said creates the theme, which should compliment the concept. When it does, unity will be achieved, and you have one hell of a server.
