So I've in all secrecy accepted this challenge, hoping I can manage to paint 5 of this lot.
For colour inspiration, well Dark Future the board game springs to mind, as do Mad Max, but also comics like Jeremiah by Hermann Huppen and Giraud's Blue Berry - so I will try and go for a dusty and worn look on the bikers etc. and a colder more sleak look on the drivers, police and militia guys.
The train in the back drop is not part of the challenge - at this point.
Until later, have a good one!
