Here's the whole army I painted. It adds up to 27 models plus two Landraiders not pictured.
A Thunderhammer/Stormshield Terminator. I used Asurmen Blue wash on the Thunderhammers to make them stand out.
For this guy, I used an experimental technique on his sword. I got the paint really wet on the sword, then swirled in a lighter color. I am still working on the technique, so I'll post some better pictures when I master it.
Here is the Librarian. It is the old model, but still full of detail. I had a lot of fun with this one.
The tricky part was making him look like part of the army even though he has blue armor. I resolved to make his shoulder and gun bone white.
To do the axe detailing I used a slow-dry medium and simply got lighter as I got to the end of the design.
Finally, the Company Master Belial. I know it's not the actual Belial but it still works. I still have to make a banner for him, but I'll do that later.
For the sword, the fluff says that the Sword of Silence was crafted out of part of the same black obsidian as the Lion's, so I went with black and a green highlight. I also tried to make the armor and gun more ornate to make him stand out. When I get around to doing the banner that will help him stand out as well.
You can get a good view of the sword here. It actually wasn't near as tricky as I thought it would be. Just some slow-dry medium and a gradual blending. I tried to keep it subtle as everything else is ornate. I like the effect as its simplicity makes it stand out against the rest of the model.
