...but you *are* sexy!
EDIT: enough fucking around. Critique it is.

From the top:
A: face is on a different perspective plane than the body in your piece. Given the underlying structure of the perspective, it would have to be tiled up more, likeso. Don't worry about realistic...er facial anatomy, this is just to explain the effect, I'm not telling you to draw it like that in the end. Now, to be fair, besides the tilt, the face would also have to be SCEWED a lot, on the same vanishing point that the rest of the body adheres to. Why didn't I do this? Because especially with women faces, it's difficult. Especially on long shot where facial characteristics are difficult to capture in few lines.
B: The collarkbones were misplaced in your original I think, given again, the pretty drastic perspective. The way the neck connects to the collarbones is important to mind, too.
C: find navel, it is two heads lower than the head, extend line to arm, that is where the joint is. Give or take for stylistics
D : that arm is difficult for me. My mind wants to go 'underutilized! but hell, what to do with it? I'm not good enough to answer.
E: I understand it may be stylistic choice, but that hand was way too low.
F: knees are hard. I'm just point it out.
G: Now here is where I don't know if you're making mistakes or if it's just unfinished. Anyway, take special attention to how the body shifts weight and maintains balance where it meets the ground. When you've rendered this more it will be easier to tell what you've got going on, but there's a chance you've made the shins too long (about half a head too long).
That's about anatomy. I have a bit of a problem with the center of gravity, she seems a bit weightless... a bit, fashion-show catwalk girl in etherial mid-stride, maybe that's the style you wanted, and she's not human so...
About rendering, from the places where it is more worked, I can tell it is good, very oily, very Painterly, a lot of people are doing that same technique, but we said, you don't care about politics. I like this, the biggest issue is that the face needs to be reintroduced in the same perspective to keep it cohesive.
