There's a bunch of little details I like here that are all the more impressive for this being a quick-random sketch. All the odds-and-ends those show how prepared she is. The light splattering in the background. And, of course, the suggestion that she's a bit young and has had to grow up quickly to deal with her world (further emphasized by her very slight leaning forward - there' s a weight on her, and it she can feel it, but she can also bear it.)
