Some Grey Knights I've been working on.
First up is a Grey Knight Librarian. Not too much converting here, just the head, banner, and the upturned hand shooting off some psychic ability. The arm is from the old metal GK terminators
I use the next guy as a Grand Master or a Brother Captain, depending on the size of the game. I loved the metal powerfist bit, which was in one of my bitz boxes forever, so I had to use it. It's a counts as Daemon Hammer for game purposes. The banner is from an old metal Priest model I believe.
