The idea is a replica of the "Bigfoot" car from Mad Max Fury Road. The monster truck that Rictus rides into battle, until it meets an untimely end running over Splendid and wrecking itself on a rocky outcrop.
To make it unique, I'm going with the Rat-Rod look of a rusty car body. My Rictus Erectus is very different from the movie version as well, but really fits the part nonetheless.
Before you can see the first part of the commission I am working on. Lots of Tau to do! But I need to go our and get a new pot of paint. It's the color for the sand on the base, kind of important to make them all uniform there!
