As with the rest of my Iron Hands, I went with a muted dark grey/black base color and all silver metallic components. I wanted to make them look basic and utilitarian (by Astartes standards), like a machine that's well maintained as opposed to gilded with superfluous ornamentation. To make these guys stand out as HQs I decided to add some gold to their weapons, which isn't used anywhere else in the standard troops. I think it'll be a small detail that pops out on the tabletop.
First up the power armored Praetor. I'm not even close to being done with sword, its going to take a lot more precise blending but it's off to a good start.
While I'm not planning on playing 30k at the moment I just can't resist purchasing some of Forge World's amazing Horus Heresy models, and this kit did not disappoint. I'm hoping to keep cranking away on these guys and have them done in the next week or two.
