so.... what do you think?"
First things, first – you don’t have enough scoring. At all. I’d be dropping the Greater Daemon, Raptors and Terminators to get some more scoring options in there, I’d be looking to get at least two small Plague Marine squads in Rhinos to supplement your larger CSM squads or completely changing them to Plague Marines as well (though 2 & 2 works just fine).
Otherwise that's about all you can do with Chaos... Consider giving the Havocs autocannons instead of missiles and you don't need the icon without the Greater Daemon. I'd also be running both CSM squads with Chaos Glory + PFist (though the PFists aren't that necessary) and the Chosen don't need Champions - all little ways you can save points.
You might as well consider running the Princes as Sorcs to hide in squads so they aren't as easy to pick out and remember Lash needs to hit now so it's less useful. On the flip side, Princes add some combat elements to your army even though they are easier to pick out and shoot down.
