I haven't done a big machine - like a dread or tank - for quite a while and had forgotten just how much fun it could be. You can be more loose and sloppy with a large model like this and there's something oddly soothing about drybrushing large areas of machinery.
The Interitus Heavy Support Walker itself is a experimental Legio Cybernetica model with two large Punisher gatling guns. At it's core is a fierce machine spirit paired with the interred brain of a former Ordo Reductor Engineseer.
I might add some extra parchments and purity seals at a later stage to give it a more archaic feel.
This was also the first time I used powders (vallejo burnt sienna pigment) and I'm quite pleased with the effect.
