when you are far away

In my opinion, I think the square crop works rather nicely, even considering the tightness at the top. Squeezing the model in like that gives a certain tension to the image, I think. It does move emphasis away from her resting her chin on her knee, as *JJohnsonPhotog said in a previous critique, but maybe simply resting is a bit too relaxed for what the photographer was trying to portray. Having her only slightly off center would be the likely choice for most other images, but I think the large amount of empty space to the left is actually an aspect of the picture that contributes to the theme, similarly to the tightness of the crop vertically.
