I agree with Trever's comments and think that the cropped version is an improvement. A couple of thoughts I will add are: (1) When you use something like railroad tracks as leading lines, try and place the subject at or near the vanishing point rather than ahead of it. The eye naturally follows these lines, which in your composition, unfortunately takes you right past the subject. (2) If you're going to have the subject looking away from the camera, the image will be much stronger if we know why she's looking away.
