Last night I threw a coat of VMA Light Grey onto all of the armour pieces from a vertical angle.
And then moved on to VMA Olive Green.
All paint was airbrushed neat (I.e. no thinner), with grey @15psi and green @20psi.
I'm pretty happy with the progress, they are looking ok and the blend from dark to light green is actually pretty good. I think I did spray a little thick, which resulted in the paint running away from edges and leaving me with some light-green edging, but I haven't yet decided if I'm going to bother with a second coat or just move on as I'm going to have to edge highlight anyway and this might save me a step. Not sure yet.
Next up is to finish the cloaks and start with the details on the armour pieces.
