These are my CSM Champions. I have around 3-4 squads modeled to have the same look. all of them are base coated red with no extra details as of yet. All of my CSM squads were based of the AoBR set. I started these off by scraping off most of the imperial insignia, and then placing guitar strings of various sizes bent to shape. Once I was happy with the shape, small holes were drilled and attached with glue/greenstuff. The Power fists were from the AoBR Terminators. Once these basic changes were made, a healthy amount of greenstuff was applied to the model and textured with dental tools.
These originally started off as my Nurgle army (around 40 models, without the red), but found the single troop choice limiting on many levels. As with most of my armies, I find that multiple like units are just not that fun to model, paint, or play. Not too bad when you have to paint 10 models the exact same way, but when you have to do 40, or with Orks 60-100, the fun quickly wears off.
