I think it looks good. I myself have a night lords list. However, I just don't see any of the cult choices (plague marines, noise marines, thousand sons, and khorne berzerkers) as "fluffy" in a night lords list. To counteract this, I gave Icons of Khorne to my chaos space marines. Either way, nice list. If you want to check my list out its under the thread "2000pt Night Lords [Friendly]".
