These are a pair of Ankhrav Drones from the plastic D&D Pathfinder Deadly Foes range. I've only repainted their faces - the rest of the models are left in the prepainted colour scheme.
I didn't even bother re-basing them but simply added some of my usual mixture to the original bases. Nice, quick and easy. (Edit: I've just noticed that I haven't tidied up the base edges. Rest assured this will be rectified by the time this post is published.)
