If you are interested, some of you asked this to me, the green was made with Citadel Games Workshop Caliban Green highlighted with Bad Moon Yellow in order to have a cool acid green.
Tomorrow afternoon I'll put this miniature on eBay as promised.
I'm quite satisfied with this model since I've spent many weeks without painting at all... my real life kept me away from my workbench!
It's time to move on... who said Black Templar Sternguard Veteran? :D
