As you're building the model, ask yourself whether or not certain things would really work. Looking at the knee armor, it still seems that it would be difficult to move around in a fight (no flexibility in the knee area, not to mention the points look more dangerous to her than to an enemy). Overall the proportions still look a bit off to me....she seems very high-waisted, maybe perhaps to how the armor is riding...and the arms look a little "off"...maybe cause you didn't block out the hands. It's super important to get your proportions right before detailing because now you have a lot more mesh to deal with when editing. Since it's a self-portrait of sorts, if the proportions are close to your body, then ignore most of what I said except for that last bit.

Don't know if you got to it, yet but the boots need shaping.
