Very nice idea. I may eventualy become a copycat for this one as I have an Archon waiting to be used for... something.

Do you think a hooded head, either from the Corsair specialist or the Dark Reaper kit might enforce a little bit more the "Grim Reaper" effect  ? Or would it be too close of a Maugan-Ra inspired model? 

I didn't have a cowl at hand. I looked for something a bit more skull like for the face mask, but this is what I had.

TBH, I thought a hood might look a little off since the cape is skin/leather. I encourage you to give it a go and let us know how it goes. I kept the skulls on the back rack to reinforce the death reference rather than use a corsair or reaper one.
