Here are one of my rare comments.
Overall, I have to say really well done, very well done pencil sketch.
The few things that most people don't do well is the use of shadows to tell depth.
Only small thing I have to say, is to make the hands and flute a bit more consistent to the others, (the details, shadows and such) mainly from just looking at the right hand (her right) that you can tell that the lines to show the creases in your hand, should have shadows because it'd be partly curled.
Overall though, very nicely done. (and you can see the paper texture, some random fibers off to the side, and the eraser remnants! of which I don't care)
