Another wonderful peice giving background for the Black Templars. I love the fact that you show the Neophyte and Initiate working closely together, as a good teacher and apprentice should. The chainsword seems a little on the less detailed side, as it's missing the powerplant for the chain drive, and the blade itself doesn't give the appearance of being chain-driven.
Also, I may be mistakened, but is the Initiate duel-wielding Bolters? I see the silouhete of one on his left, so it looks like he's carrying two.
Neophytes are the Black Templar recruits, Scout Marines in other chapters. They lack the Black Carapace implantation, so they wear a modified version of carapace armour, not the full power armour of the Initiates.
