Rogue Trader Era Imperial Guard

I needed a few miniatures to test paint, so I dug around in my 15+ year old bits box and found these minis. I have no idea what the orange guy is supposed to be, but I painted him up in a star wars suit to see how orange took the dev mud wash. I have never been good at fabric, so the guy with a cloak was an attempt to see what I could do. These are not well painted minis. I think I may have learned a little by painting them. Hopefully I did, since that was the point. The question is what to do with all of these guys now. I already have randomly painted orcs that I used for testing!
