Hi Kahrtolann! Yes, I posted them on Warseer (http://www.warseer.com/forums/showthread.php?t=292496), GW-Fanworld (http://www.gw-fanworld.net/showthread.php?t=151772) and of course on my blog: http://brushandminiaturetorture.blogspot.com/
You can find a little tutorial for the Iron Warriors on each one of the websites.

In fact every Terminator has at least one area with chevrons.
