Scuttling ahead of the Imperium's giant war machines and Titan engines in a swarm of flesh and metal; the Skitarii are a really interesting mash of weaponized steam-punk aesthetic and ancient technology. I thought they'd be a great entry point for me back into the world of painting/collecting.
I chose the weapon, head, and various war gear options for the models with some vague approximation about their intended role on the battlefield.
I've been sticking to the traditional red "Mars" color scheme; it was a close call between that and the orange of Ryza (which I'm honestly still considering for my Cult Mechanicus).
What I'm enjoying most about the models is the number of assembly options and their ability to look great in a variety of poses.
