Agree with SeanC, the face is ...not quite there. It seems to me that the skull is not quite big/high enough. The eyes should be the half-way mark, and in your render the eyes seem to be quite high, almost 1/3 down from the top of the skull, and that's taking in account the hair,btw. And the nose seems to be a bit on the too-long side.
Suggestions, make the head (sans hair) a bit wider, drop the eyes and nose bridge down a bit -- more in the center. And put a eye's width between the eyes. Would help to have a c.u. on the face, front, side and 3/4 view to better see if this is what it needs.
Either the arms are too short, or the hips are too low. The elbow joint should be @ the waist. the tip of the middle finger should come about mid-thigh. That would place the crest of the hip above the wrist.
I like her, nevertheless. Still a bit to go in anycase. Just wondering, did you use rotos when modeling her? I've returned to A:M after about 10 months and have been modeling like crazy and haven't been using any rotoscopes for reference. It was last night when I looked at my latest model (about 10 hrs of work thus far, still a noob) I saw that a lot of porportional stuff was just plain wacky or wrong. This morning I whipped up a front and side 2D drawing for the face, placed them in and things are a lot better. There's something to be said for working from a 2D illustration to make a 3D version it. Not to mention this helps me to keep the modeling "on model" so to speak.
