Sorry I cannot be more specific, I hope this helps.
Dont be sorry, it all helps

Maybe my Google-fu is weak, but I didnt find a whole lot online about how people painted these so any advice is welcome.
As the mats are supplied in a primer grey like colour, I am likely to paint the Broken Blacktop predominantly with dark washes directly over that, to hopefully end up with a road/asphalt like colour.
My plans for the Scourged Forest involve some drybrushing of the yellowish, deserty colour and some detailing followed by a dark brown wash or two I suspect. Maybe a further stage of drybrushing, but I am not sure.
I am considering trying to (very) lightly spray on a couple of other colours before the drybrushing stage, to break it up a little, but I have had little success with this sort of thing before, so I would love some input.
Also, before I get stuck into the painting I hope to hear from someone who has actually already painted one, just to try and get some pointers.
