Thanks mate! I worry that I overwork the lines with these kind of pieces. I have a bad habit of getting caught up in the fine details, and end up losing a lot of the spontineity and life. I tried to keep the lines loose and fluid wherever I could, but there are still loads of places that are too "clean".
A great depiction of a Grey Knight, but I think his smile is a little...maniacal. If he was a Flesh Tearer, I'd buy it, but since he's a Grey Knight, I think his mouth should be drawn into a thin, grim line or open in a vocalization of righteous fury. Ex: "KHAAAAAAAAAAAAAAAAAAANNN!"
