I had a few weeks where my job took all the energy and concentration I had, but summer is here and I'm back at my hobby desk.
The second guard was originally going to have a visible face, just like the first one. I even made a head for him but scrapped it after I decided it wasn't up to scratch. Then I hit on the idea that the heads from the Sicarian Ruststalkers would made good Mechanicum issue gas masks.
Other than the different head, he was made in the same way as the first Household Guard; a Solar Auxilia lasrifleman as a base, backpack from a Forge World Chaos Renegade and lots of greenstuff.
As always apologies for the terrible photography, thanks for looking and your comments are massively appreciated.
