This is GLORIOUS! I couldn't get into playing the tabletop game, but simply for their look and role in the universe, I am a big fan of the Space Marine! Just as I am one of the Daleks! This one may look irregularly bulky, but to me, that just makes him look MORE like a 40k dude! Your play on colour is fantastic (besides the eyes, which look blotched) and you clearly have a good understanding of posture and anatomy. Good work!
