OK, I don't wanna rain on your parade, but I will
Everyone gave you praise, I will spice it up with a little critique
These models are really awesome when it comes to the whole theme idea, posing, kitbashing etc, they look like a bunch of real mean mothers
But one thing you could try to improve is the brushwork itself - it is a bit sloppy here and there, the red elements have smears of black and the other way around; the blue eyes could use some "lensing", as they are the focal point of every mini, standing out of the black-red mass like this.
Also the metal elements could use a little more careful shading and highlighting, with deeper shades and brighter, more crisp highlights, as without it they tend to look aluminium-dull.
Third and the last thing - battle damage and weathering. Now these are pretty tricky things to do and the "less is more" rule pretty often applies here; such extent of battle damage at first sight makes the models look not weathered and realistic, but just sloppy. Remember the scale - when a hard surface scratches on some concrete, rocks or even combat blades, the scratches will be relatively small and subtle, while on your models it looks like the paint was not scratched but peeled in places. Also the rust needs to be subtle to look good, it's much better to build up the rusting effect with several layers of very thin wash than with one thicker one because of the tidemarks - one thicker layer doesn't look like a rust buildup but like someone just painted the area rusty brown. The same rusty brown caked on the minis... Well I suppose your goal was to make it look like splashes of mud or dried blood, but honestly my first thought was "someone was throwing feces at them"
Especially that you weather their torsos and shoulder pads with it, but not the legs, which should be first to get caked with mud, come to think about it. And if it was supposed to be dried blood - well the colour is not exactly right, dried blood is more blackish-dark red than rusty brown.
Honestly this amount of battle damage and weathering rather spoiled the overall good effect of your army instead of helping.
All of the above does not mean that I necessarily can do better, mind you, I'm criticizing as a viewer, not as a painter. Well, maybe as a viewer with some painting experience and real lots of theory absorbed
Now hate me and kill me
