The thing about the Angels Sanguine...

From the Lexicanum:

The Angels Sanguine are known never to remove their masks in the presence of anyone outside their Chapter. Even amongst their battle-brothers, their faces are usually hooded.

So this poses some challenges when fielding a few marines. I have always hated bare-headed models...it just seems really, really dumb. I understand why, but it's still silly to me. So when I realized that I needed to field a sergeant in my tactical squad, I knew I had to modify the AoBR sergeant a bit to make it work in a fluffy way.

This is the sergeant from the Black Reach box:

I only have CSM heads in my bitz box since I've never collected regular space marines before, but I found sort a neat looking one that didn't have spikes or horns. In fact, it looks a bit like a chaplain helmet, but not quite as skull-like.

I dremeled out the head and neck and voila (sorry, this was taken late last night on a cell phone):

Each time I do these little, forgiving projects, my confidence builds, and I want to do more. I still need to figure out the whole mycetic spore thing.
