Getting down to the wire here, so updates will probably start coming a little more frequently until the project is complete. My deadline is March 28th - the day of the Kill Team tournament. It is in the afternoon, so if absolutely necessary I can still work on things the morning of, but I'd prefer to be finished the night before at the latest.
Anyway, on with the show! (Thanks to Turaxa for the helpful suggestions - they made for some nice improvements!)
I have added an Inquisition symbol (using a styrene I beam from my local hobby shop, sliced nice and thin...) to Belsavis' shoulder pad, and added an ornate shield to his waist as well. I wanted to keep it somewhat plain, but mark him out as an Interrogator and a higher rank than any of the others, so I thought these touches would do the trick.
I found a smaller pistol holster for Shick which I like a lot better than the huge one he had before. I also added a small strap from the bottom of the holster to his belt to make it look less "stuck on".
I clipped and filled the shell ejectors on both sides of the hotshot lasgun Stormtrooper, further hiding the look of the bolter it was converted from.
I added several bits and bobs to D'Altann's backpack, as well as an additional strap and another wire connecting the backpack to his chainsaw arm. Hopefully this makes the backpack look a little more like part of the whole rather than an afterthought. I also built up his neck area a bit, and hope the paintjob will make the large head blend in a bit more.
I added some green stuff blocks to the top and bottom of the shield connection points for the Crusaders. The intention here is to make it look like the magnetically attach to the armguards strapped to their forearms.
And here are all three of my objective markers, thanks to a few bits provided by one of my local gaming buddies and my last servo skull. (Eventually I plan to make a total of 6 of these, but only need 3 for the tournament. I hope to get some of the servo skulls from the Space Marine Devastator kit to have even more variety of bits here. Obviously I'll need to acquire some more Tau bits as well, but that can all wait.)
