Pretty good.
Overall, it's shaded pretty well. The clothes wrinkle realistically and the skin's shading is accurate. There are some problems with it, though. I feel like there's way too much contrast in some areas, particularly the stomach, the chest, the face/lips, and the bottom shirt. It almost makes her seem metallic. Also, on the gold stripe on the jacket, You have highlight patches there that don't seem to match the light angle of the rest of the picture. I think they should be more centered on her arms and that they shouldn't be touching the black linework. And again, tone down the contrast a bit there.
You noticed that the waste was way too thin, which it is. The thighs are also too thick for a woman of that weight. She's not overweight, so I'm assuming it was meant to be muscle, but they too wide for a woman. The eyes are far too large. And, they're not shaded as if they were balls, which they are. Shade the corners of the eyes so they have a roundness to them. Also, there's some weirdness with the right nostril. It's not shaded the same way as the left so, so it looks substantially smaller.
For the linework, I suggest making your lines thinner if your figure is going to be shaded this realistically. It just doesn't match the style. I think you can also leave out the lines in the middle of her stomach, chest, and on her inner thighs. Those lines are necessary when you're drawing cartoonish figures, but when you're shading with this much detail, the shading will take of itself. And, on the hair, as well, on the left where you have that little tuft sticking out. It doesn't look realistic because of the thick lines. As a general rule that I've seen, the more detailed your shading is, the less you should be dependent on lines. You should have thinner lines and less of them.
But, overall, it's done relatively well.
