May I ask how you painted them?
Of course you can. The metal's been basecoated with Boltgun and then washed with devlan mud followed up with a Leviathan Purple wash. Be careful with the purple as it gets overwhelming quite quickly. What I tend to do is dip my brush in the wash and then touch the tip against a paper towel. This sucks out most of the paint and prevents the purple from pooling in the recesses as it normally would when applied as a heavy wash (I'm not sure I'm getting this across properly. If not, feel free to ask again.). The purple is there purely because of the yellow hazard stripes and because it adds some subtle colour to an otherwise very monotonous army. Yellow and purple are across of eachother on the colour wheel so they tend to go rather well together. Just don't overdo it.
After the wash is dry, just highlight again using Boltgun, followed by Chainmail and Mithril. If you want to do this a bit faster, just highlight with Chainmail and you should be okay.
The brown metal is just basecoat Tin Bitz, wash with purple then highlight with a Tin Bitz/Mithril mix.
Lovely work. I can definitely see the skill here even when I'm not crazy about your choices.
I think your blending is really well done. And your attention to detail is excellent.
I think the damage in the hazard stripes looks funny, and extra busy. I think your armor silver is too bright, but it's possible that's from the flash. Or at least the highlight towards the armor edges seems too bright.
I'd love to blame my crappy photography skills for the armours brightness and in part it is indeed the flash's fault. But as I highlighted up to mithril I suspect they'd still be too bright IRL. I have to say that I don't mind the brightness as it helps make the look dirtier because of the washes in the recesses.
As far as the hazard stripes go I think you're right. I was already going to paint the beaks on the helmets in bare metal again as the stripes don't really work on there, but I probably went a bit overboard with the stripes altogether on the last three. The scratches will remain there, but I will be using a different method on the next ones (the sponge method).
In any case thanks for the feedback. I'll be working on the next ones in the next couple of weeks but in the meantime here's something I'm working on in between for fun. :D
