I thought I'd try my hand at drawing a Space Marine... but then I thought, nah, let's go for a Traitor Marine instead.
Even after much deliberation, I was unable to decide exactly which legion (or chapter) he should be from. As the drawing evolved further I started to go with a slight Word Bearers theme, but nothing too obvious. There are one or two hints at it about the picture.
What I wanted to capture most about the character was that he'd been around (and exposed to the ruinous powers of the Warp) for a bloody long time.
