(Khorne is red and brass, not gold )

Berserker is looking nice though, you're much neater and smoother with your paint work.
The bone bursting out of the Dread makes it look a lot more chaos'ey too. I'd really suggest you start conversion work before assembly though (eg, cutting off Imperial Aquila's, ad-mech symbowls, purity seals, etc) to make your life easier.

The purple scheme is good too. SHADE THAT METAL ASAP
