It seems my original Executioners thread is archived so I have to start a new one, which is ok since I'm pretty much redoing the army and actually finishing it.
The left is the original, but Reaper discontinued the blue steel I was using.
The middle is what I ended up working with, which looks more like metallic Crimson Fists than Executioners.
The right is my newest attempt, which I think is much closer to the Imperial Armour book (it is more bluish in person).
So my goal with this is to repaint just the armor of what I have already done (6.5 tactical squads, 2 assault squads, 1 devastator squad with extra heavy weapon options, 1 sternguard squad, 2 dreadnoughts, about 20 terminators and a full command squad) plus finish out the last 1.5 tactical squads, a damocles command rhino, and 8 rhino/razorbacks.
