Deep space missionary

Some more assembly on the travelling preacher today.

So here he is, part man, part void suit, part jumble of religious paraphernalia and (dodgy) relics. Travelling the universe to teach imperial citizens the proper worship of the God-Emperor.
But the universe is a dangerous place, even for a man of faith. So his hotshot laspistol and pump action shotgun are a standard part of his travelling kit.
Judging by his stern look (and drawn sidearm) someone is getting schooled on the finer points of Imperial dogma....

He's only tacked together temporarily, as he obviously still needs some work:
-The rods on his pack will get wicks and molten runny wax sculpted on, to be candles.
-The book on his staff still needs to get properly attached to his staff with some metal bands.
-The foil strips on his shoulders will be purity seals, they just need the greenstuff wax seals added.
-I'm thinking of adding a brass etch aquila to his gorget.
Then there's the matter of his stomach plate and the upper part of his pack. I'm not sure if I should keep them empty to maintain the void suit look, or put a purity seal on those as well?
Maybe dump a spare book or ecclesiastical icon on him somewhere while I'm at it...
