From Curt:Very cool! These fellows have that armed minion look down pat. I really like the addition of the green trim - it brings some visual interest to otherwise very dark figures. My curiosity is piqued regarding your experience with the Vallejo 'Heavy Charcoal'. I'll have to nab a bottle and give it a whirl as I'm always on the lookout for alternate ways to shade dark tones.
Great work Simon.
