This stuff is great. I love the custom color scheme, and the application of the hazard stripes. My only gripe is that you've got decals from everywhere. There are ultramarines, blood angels, mechanicum, iron hands. . . I feel like that'll undermine some of the unity in your scheme. My advice would be to standardize a bit and give your force an organized feeling. Unless you are going for something a bit more haphazard in their iconography, if that's the case then proceed on to greatness.
