Unexpected World Eater

I really need to stop getting distracted. I ordered some bits for my Sons of Horus, including some WoC Marauder arms for the axes, intending to finish up a squad this week, but after clipping the weapons off the arms I found myself left with some bare arms. One thing led to another and i built this:

It's World Eaters character of some description, thrown together from bits lying around my hobby desk. Once he was put together, i figured I may as well paint him up as well:

I think he looks great. The GW blood effects work really well on him. I'm not sure what I'm going to use him as yet. Had I planned a bit more, I could've given him a plasma pistol and used him as a pre-heresy version of Kharn, but I never really think these things through. I might expand him into a full squad to be used as a small World Eaters allied detachment, but I'm not sure yet.
