I love this shot, and full respect to your concept, execution and props to the photographer...
However, as someone who knows the back end of a camera and the insides of photoshop - there is no way that some significant levels & curves adjusting hasn't been done to make the eyes pop. No camera can capture such a dynamic range: absolute white of eyes to full black of lashes, with detail thoughout the midtones.
There is no problem with any of this. I'm not criticizing, I just thought if you are going to make a point of saying "no photoshop done" then it just makes people look more for signs of editing. Just OWN the image, there's nothing inferior about getting some digital tweaks - it's not making you any less amazing as a model, just compensating for the limitaitons of camera technology (or bridging the gap between camera output and artistic vision). :)
