First off, I'm not much of a 3D modeler myself but I have done some modeling so I know how difficult it can be and more importantly I look at a lot of 3D models so I feel I can give a fair critique on one.
I like this very much. The detail in the outfit, especially the fabric wrap, is amazing. I also like that there is different materiel which gives it a more realistic look and feel. I've seen a lot of similar models where the artist used only leather, steel/metal, fabric, or something similar which is good and all but that's not very realistic.
Your proportions are right on and I like that you didn't exaggerated the breast size. Women warriors would have less body fat so they wouldn't have breasts the size of hot air balloons. The hair is fantastic and I'm guessing took a lot of time.
However, even with that said, I wouldn't say this was very original. There are a lot of artists out there producing their own version of the "Sexy Woman Warrior" (I'm working on one myself in fact, lol) and besides a few details, when you strip it down they are the same.
Your technique is excellent and I can't find any flaws in your rendering but maybe I'm just distracted by the model. Overall I like it very much and think it is an excellent piece of work.
