Another small update - the keeper is nearly much finished.
Unfortunately I didn't have that much flexibility with the head as I had to pin it in order to build it as so I really only had three choices looking to the right, left or straight ahead. In the end I did glue his head in the cliched position because unfortunately it did look the best. I've also added his respirator, connecting pipes and a holstered pistol. I changed it from the initial design which would have had the pipes coming from the two outlets at his chin. I did this because despite my initial feelings that the outlets were too big they have grown on me. I've relocated the pipes to just behind these. Also debating which side to put the gun.
I think in 40k games I'll use him as an advisor or sanctioned psyker.
