Looks ok.
I prefer the marauder-warrior-ogre-marauder inf brigade, but try that one out later.
A double sorc AngerOfTheGods-bomb is a very effective defender. And you have the points for it.
1000p? These battles tend to be over in 30 min, but that is probably no news for you.
2 hounds for every 1000p in a Chaos army is the way to go. These little basterds are awesome kamikaze units and they do give you that extra numbers when counting break points.
Maybe change the Knight for another Chariot and add one Ogre? Break then becomes 5.
