so, like d-art said, a bit more hips and butt, the torso itself is a bit to long, and well, you'll need to take in consideration her left leg's muscle according to it's angle, since it's not the same as her other leg.
now about that neck, muscles and tendons really don't show unless you're doing some freak disembodiment yoga posture really, so aside from the clavicules, you really should see that much detail there or it will make her look under nourished or heavily muscled....but of the neck only xD
and let's demistefy something about cleavage shall we, the boobie line thing? It takes some C and up to do with a good pushup bras or b and under with plenty of cushioning, either way, her colar would need to go down a bit for it to show to. I personnally thing she looks nicer with out, it brings out the warrior side of her rather then the sexy beast.
and hair volume now! she seems to have plenty of it, so if you want it to look good, have some curve in the hair line, so that the hair look like it's pushing up rather then it's floating above the hair line.
anyway, a picture is worth a thousand word right? ^^

I think it's going to end up looking really nice, you've got a nice character design there, I like her looks. Keep it up :)
edit; I forgot! Sword hilts (is that what it's called) are accually perplexely long, her's look like a two hand...so you want to make sure there's enough room for two hands.
edit edit: and I'm sorry if I ever let slipped some french words or words that don't exist, I don't know my anatomy and body parts very well in english.
