First reaction: Lots of plate for a Dark Elf. Most of the time, dark elves favor stealth and speed, so that threw me for a moment.
Second: Her neck is pretty thick. That throws off the elven proportions. It's generally supposed to be thin and delicate *seeming*, though with good muscle tone. Drow seem to be more bulky sometimes, but...
Given a drow society dominated by females, I would just propose that most female warriors would probably make sure their gender comes through a little more, just to help intimidate the weak males.
Also, she's practically holding the crossguards of those weapons. There should actually be the sense of some space between her hands and the crossguards, its less tense and allows more flexibility of movement.
Also, without a background context the impression her feet give is that she's leaning backward, but the rest of the body seems straight.
Okay, positives time.
It is a solid humanoid form, and the armor and weapons are awesome. The deep-set, wrinkled eyes give an impression of angry, restrained menace; the cat-like slits just adding to the demonic violence.
The eyes are really cool.
