I finished 3 of 6 marines for the slannesh squad. The other 3 are pretty much going to be quick to finish since their isnt much added to them, besides of course the guy with the power scythe. For him i plan to do some O.S.L on the weapon. I also finished their accompanying rhino.
I just did some freehand on the top, and on the chaos banner on the side. It really stands out from the dark red color of the rest of my vehicles. Can you guess what the banner says?
