it's a pretty nice rig-up, but i do have 3 suggestions:
1) make a seperate portrait file for her. A portrait where she talks would be better fitting for an organic unit, IMO.
2) the facemask on her chin could use a little fix in the skinning. On the cheeks, the golden strip between the facemask and cheek is more visible. On the front-part of the face it's lesser visible, except from close view.
3) the shield's height should maybe be lowered a little bit. In a few anims, it looks like the one top corner would sting her neck or, like in the Stand Ready anim, the shoulder pad goes through the shield.
My suggestions are just minor issues, rather perfectionising than essential. It looks pretty good without them as well.
