I had a bit of a block going into this set, as I wanted to have something subtle show the difference between the two squads, without making them look like they were from a different chapter. In the end I chose to make all of the jewels a different color (Lorenzo's squad has blue jewels, rather than the green ones here).
Also, I updated my Librarian Calistarius. I had originally painted him with metallic metals, and without dark lining. Last thing I did on the set was paint him in Non metallic metals to match the rest of the Space Hulk set.
