This is lovely... I love all the stripes and that focus on her eyes... The rear one seems a tad bit 'cooked'... but since I'm not voting, I'm just enjoying it all!
Tack sharp from her knees back, and I'm assuming you wanted the shallow DOF to draw attention to her face...which it does. However in this particular case I personally think the image would have been even stronger than it already is had it all been in focus. Her left hand is fine, but her right hand, fingers and rolled up portion of the sleeve are too much of a distraction from the rest of the great shot.
The B&W conversion is excellent along with your title and the look on her face. Love all the stripes.... 8
