Cellist

I was travelling on the tube when I saw this lady leaning on her cello (I think it's cello, right?) and I was waiting for her to look at me. And then she turned and looked straight at me, so I quickly pressed the button! I don't know what's in this look, tiredness may be... I've taken this pic with iPhone, so not great quality or sharpness, but there's something in this look that caught me.
