My opinion...and I'm a RAW beginner with an undeveloped eye...is that the girl is exquisite. Focus might be a little soft, though. I would want to lose the background though.
I would -- again, please note: BEGINNER here myserf -- I would try black and white, hit the contrast a bit which can sharpen it, and then perhaps try to blur the background.
ETA: Neither of these are better (or even as good) as yours, but this is what I tried.
Rachel,
Good work! You have demonstrated that an "Arc of Intent" can start at any point in an expected chain of creativity. Your first image is creative and I like it. The softness around her allows one to focus on the girl thinking. It works. Chalotte's work is harsher but itself also effective. Two totally different and worthwhile results from the same image.
This demonstrates our responsibility to ourselves to invest more effort to have the picture express what we might think not just what the engineers in Japan build into the personality of the camera.

BTW, what blur did you use? Could you post your photoshop layers?
