Why should we bash you ? Maybe cause you're writing all the equipment's costs in details ? It's against the copyright of Gw your know, just write the total of the unit, we should know how much each equipment cost if we post to give you advices.

Following my own tastes, I:
Would haved bought warp time to the daemon prince in place of the mark of khorne, make it more deadly than than before.
Your khornate lord is tons of fun with a pair of claws instead, as it give him another attack in Hth.
Your termies are ok if you make them go in the land raider.
But that's just one unit, and if you make the lord go with them they must be just 4 termies and the lord to fit in the land raider.
The other unit should stay cheap, with a fist and heavy flamer, and the rest standart power weapon, and combi weapon, plasma or melta, as it's the only way to make them earn you some points in deep strike.
The land raider can go without any further enhancement, havoc and possession isn't this benefic to such an armour.
With a predator, you usually go for autocanon and heavy bolters, cause of the enormous cost of lascanons, and you already have some on your land raiders.
If you can make room for three termis with combi melta in can do as well as the lascans of your predator.
Vindicator, yum, tasty.
Khorne's berserks should stay 8 men, a fist, in a rhino, if not they're not gonna join the fun till it's too late, and your land raider make a juicier target so your rhino can survive long enough.
10 men units of csm to get an heavy weapon ? Not this good in this edition, but do as you like, as you've no room for oblits, and this unit can keep your table's quarter just fine.
