Here's another few quickies, my oxidation beasts! I call them Ol' rusty and Oxide:
Bases are miliput sculpted to look sort of rock like. I also took some spare shields and weapons from a sprue of super cheap plastic guys I got on ebay a while back (Zvezda stuff). Cut those up a bit and added some sand mixed with brown paint for a rusty look.
My light box definitely needs a bit more light as I can see stuff ends up in shade even now, but it's not as bad as before.
