These are really great! The blue where you usually see gold is genius and I never would have thought of it but it looks fantastic. Few critiques though (not that my miniatures are any better); The swords look a tiiiny bit obvious that you've masked them to airbrush, but I know it's one of the most awkward things about airbrushing and is a skill that I'm still working towards getting right. And a few mold lines appear but very minor.
P.S The eyes are really well done. I might have to use this colour scheme in future!
P.p.s You managed to take a pretty good photo with the flash which is almost impossible for anyone else so congratulations ;)
