I like it, though, I feel that her arm might be a tad long. If you stretched it out into its full length, her hand would almost touch her knee, arms aren't that long, are they?
Plus, she has no butt :( But that's not an error, it's just a matter of personal preference for me. (though her legs feel a bit short compared to her quite tall torso, a problem I also make when drawing stuff :\ IRL, I have quite a long torso compared to the length of my legs, something always present in my drawings. People tend to draw themselves into their drawings, something which is interesting :>)
