I decided to work up a Space Marine army after listening to a bunch of Horus Heresy audiobooks over the past month. I decided on doing Imperial Fists - and after looking a few tutorials using the new Citadel contrast paints, decided to go that way. I started with the Prospero box sex to form the core of my army - these guys are Heresy era (30k) in MkIII iron armour which I think looks cool and fits the meta of the Imperial Fists. I also did a few Knights and a Titan for Adeptus Titanicus to round out my full maniple. I experimented with the new Citadel technical paints make the bases a Martian earth theme.
Some Sisters of Silence for good measure.
