It means it looks like the pic you posted (reference one) but gone wrong. You should use some patches for those curve things, and use better textures, not the orange Bespin ones. Coruscant is mostly gray/light blue, the orange/purple sunset is what makes it do that. Colored lighting on light blue/gray textures would be best.
Clarionet, n. An instrument of torture operated by a person with cotton in his ears. There are two instruments that are worse than a clarionet -- two clarionets.
