Cheers man! Aye, it's vajello flat brown with increasing GW flame orange for the rust, then the browner and blacker dirt is vajello brown and black shade.
Cheers pal! Sorry for the massively delayed response! The bases are the standard ones from the Sedition Wars minis themselves http://studiomcvey.highwire.com/product/swb1001-vanguard-bases but can be bought seperately here. They're a mad plastic resin type effort, but they're detailed and look sweet! They have a few other types there too, certainly fit for 40k/necromunda style gaming!The red does look good mate, personally I can't stand the mini it's just too WFB for me. That's a really good idea going more with the Astral Claws route for the contrast. The flame effect on the shoulder pad is a nice touch.
One question, where did you get the bases in the previous post from?
