I've gone for mkIV armour in the majority for my force as it looks smart, and reasonably streamlined which suits the Night Lords style. Plus the assault marines look ace!
Currently the Legion symbol shoulder pads are blu-tacked in place. I had thought about moulding my own Night Lords pads from a metal chaos one, but the quality isnt great, so i'll keep them smooth for now until Forge World (eventually....) release some nice sculpted ones.
So, without further ado, i introduce the Third Claw of 7th Company, VIII Legion Astartes.
