The exception, of course, is in the light teal accent, which I thought was a nice counterpoint to all of the warm colors, while not being something too rich like a primary blue. The varied placement was to emphasize a little individuality, while the consistent color was to unify the group. Also, I admit that I just like painting teal.
For materials, I went with a much lighter armor color than I'd normally do for this sort of sensibility. Either a dirty white paint job, some sort of future ceramic or plastic, or just a light metal, I wanted to avoid a grungier look that might come across as scavenged rather than worn.
The minis went together quite easily, most fitting with no effort; a couple fitting with a minor waist gap; one of the aiming poses would have been nice to have one fewer pieces, but it still fit cleanly.
They're cast in resin, with just a little give, that felt right for gaming pieces. Cleaning was almost negligible, a couple barely-off mold lines, and then the various points where the vents/sprues were. These were well-placed, mostly where you'd be gluing parts together anyway, or on non-detailed surfaces. Either way, a sharp knife was plenty.
Note: I was paid to paint the above models, but the review was my decision since I liked the quality, and I never accept payment for reviews.
