Ok, first off, you really improved a lot since the first entry. The shading is done nicely, not overdone, and in the right places. The legs are drawn nicely and well proportioned, I particularly like the shading since it captures the light source quite well. i also really like the shading for the face, it gives the face a nice contour.
Now, improvements, I'm going to nitpick here since this is probably the last time I'm critiquing your art unless you decide to make more art threads in the future. First, the clothes. You did add folds, which are nice, but now the folds themselves are the problem. Your folds don't really fold, they are just lines. You didn't make what I call fold bumps on the outline of the clothes. While you could get away with that usually, it's still a good idea to draw some, usually where the cloth is being compressed. Also, keep in mind folds appear both when the cloth is being compressed and stretched, and careful not to overdo the folds.
Next, the hands. These are pretty well structured compared to your previous sketches, a bit of an issue with the left hand is that the fingers seem a little too short.
The hair is a bit iffy here, I can see strands, which is nice, but there is too much crisscrossing. It lacks flow. Yes, hair is not always perfectly parallel, but this seems like you tried too hard to make each strand go in a unique direction. This is actually the opposite problem to the folds; for the folds, there wasn't enough detail, for the hair, you placed too much.
Overall, the sketch itself is pretty well structured, and well drawn. However, it could benefit from improving the fine details, but be careful not to overdo the details. A good mantra to follow is "art is suggestion, not replication". All you need to do is suggest the details are there by placing a couple of details, enough for the viewer to notice, but not too much as to clutter up the sketch.
P.S. You seemed to have switched the left and right feet.(^ _ ^)
