Yo, good job with that character, but I've observed a thing or two about it that might help you make it better.
First of all, you need to break the symmetry. Add some design elements, like soldier's 76 eye-visor, or different sized or designed shoulder pads, or bracers, or all of it. Also, hair and eyebrows are never symmetrical. Slight change in shape of eyes wouldnt hurt either.
Also, eventho I like your lines in the abdomen area, they could use more pop and be slightly more interesting as I will show on my sloppy overpaint later.
Speaking about abdomen area, those plates seems to have slight inconsistency with its edges (look for yellow on the pic) You gotta have them all either sharp or smooth. Try to use orb_cracks instead of dem_standard for a change and see how it goes.
The design on the shoulderpads doesnt fall into a straight line from the side perspective, you can fix it quite easily with a move brush of a big size, and it will feel much better.
Also mechanical bits around her ankle could use some cleaning, do it with either clip or trim brushes (those you get if you press ctrl+shift and go into brush selection) or do retopo with creasing.
Also foot could use some work to make it look like it distributes weight properly. Some goes on her high heels (which should be flat btw, because you wouldnt want to penetrate soft surface under your leg and stick an inch or two deep in soil whenever you walk). But most of the weight goes to the point between metatarsals and phalanges, where you have a fat pad or something. The big finger "looks" almost up, the pinky "looks down", while the rest of em somewhere in between, making a nice curve. Eventho she has non-human legs, but making her fingers have human-like angles to them would make it much more appealing.
Here's an image, really hope my critique will help you
