First and foremost I bid you welcome Brother Slaughterer. As a fellow devotee to the Blood God, it's nice to see my kin here.
Secondly let me say I'm rediculously jealous of the amount of Forgeworld you're packing into this warhost. I have 2 FW dreads, 2 units of Berzerker upgrades, a unit of Terminator upgrades, & Big Z himself. I do not have the Daemon Prince [ I almost hate you because you have this one ], the doors, or the Blood Slaughterer, or the rules for Big Z.
Next, I like your painting style. I myself prefer a darker tone for personal and fluff reasons. I see what you've done there and it pleases me. You're style is clean, crisp, and sharp. Your red is rich and has plenty of shade, depth, and tone. Kudos, keep it up.
Now on to your army composition. Just a few things here you may want to consider.
I run all my Berzerker units at 8 strong [ Khorne's sacred number and all that ] with a converted Beastzerker Skull Champion with a power weapon standard. If I face 'wing" lists or heavy armor I replace him with a power fist instead. Also, I run 2 plasma pistols in each unit. They're nice to have on hand.
I run 4-5 units like this for more scoring units. Your list has 3 and that could prove problematic for you in objective based games.
I run Kharn as a mandatory HQ choice alongside a Daemon Prince with MoK & Wings. He's 165 points of asskicking fun and so worth it.
Everyone gets a rhino...Everyone.
I don't know how you have your dread equipped but I run mine with dual CC arms.. I have shit luck with fire frenzy rolls and don't chance it anymore.
All that being said I'm keenly watching your plog here as I tend to " borrow" ideas from fellow World Eaters players. Should you do the same sir, you can find my work at the links listed below.
