Thanks! I'm still very much a beginner in figure painting. At the moment I just try to keep it simple. Neat base colours. A citadel wash, and then repainting the base colours on the high points to highlight. Really easy. Oh, and a matt coat to dull down the wash.
Those figures look good - you should get them finished. I don't know what that gun is, but it looks excellent. I like your white-wash.
Cheers!
