As soon as Forge World released this model I knew I wanted one! My amazing other half bought me one for Christmas, and I've just finished it.
It has the same basic colour scheme as my other large Necron models: I used a piece of firm sponge to stipple Warpstone Bronze over a black undercoat, and then drybrushed with Brass Scorpion, finished with a highlight of Vallejo brass. Simple but very effective!
