Good details, bad proportions
I'd have to start off by saying that she looks slightly unusual. I thnk there's something odd about her face and her upper body. They just don't seem right when I look at them.
The details on the other hand are pretty neat. They look like a color pencil sketch + shading and shadows. But speaking of shadows, I think you didn't place a static light source. Shadows don't seem to be consistent An example can be at her left calf. There's shading on her calf, but not the opposite side. That's pretty strange. The shading on her shirt is noticeably much darker than the rest of the shadows.
Overall, the details are fine, but the drawing needs a little work.
