Scary army! The problem is troops though. At one time you could make a list with an absolute bare minimum of troop choices, but now that isn't going to cut it. For 2000 points twenty six bloodletters and eighteen cultists isn't much. Two Khorne daemon princes, a bloodthirster and helldrake would scare the crap out of many opponents, but if they're single minded in pursuing the mission objectives and focus their efforts of taking out your troops I think you'll very often find yourself with no troops left to capture objectives.
400 points of troops is just a bit too light for a 2000 point army in 6th edition. I think I'd look at removing a daemon prince and reinvesting those points on troops
