I've 16 Poxwalkers and although I'm not following my completely diverse skintones there is some subtle differences in this group. Half of them are Stonewall Grey flesh coloured, with half of them red washes.
The other 4 are green washes. I'm also trying to replicate my Free Radical Collective Genestealer Cult uniform scheme.
These guys are being infected from the same population, in fact the second from the right has an almost Tyranid arm [maybe with a bit of Kroot thrown in]. I like the idea that Nurgle is trying to find some way to use the Tyranid DNA [I know they retconned them not having DNA, but whatever] as a viral infection -hence these mutants.
The other half of the group is basecoated with Army Painter Skeleton Bone. Split again with half shaded green and half shaded red.
Obviously there is red here also but it's the underlying shading. I've then added a bit of Skeleton Bone as highlights to a couple of them [see if you can work out which ones] to see how that's going to work.
Here's my red shaded four, lots of beatsticks/hammers between them, which I hadn't noticed before.
That coat may prove challenging.
So, significant progress of some of the simple and necessary basic elements. I think it's the orange stuff next. Get all the uniforms done and move these along.
