Image Description: I liked the idea of using dark colours on this guy, but i wanted to use a metal on he's body to still keep the face that he's a necron. Puls the colour adds to the effect of him being from the stars.
Looks alright, yet with my Nightbringer, I went for a shadow grey / fortress grey model like GW's, to give a calm, blue colour. You don't have to make it look like a necron, as it is a c'tan, who took over the necrotyr empire to rid them of their cursed skin, trading it for cold metal, and slavery. Cool. :D
