I believe this photograph is technically and aesthetically remarkable. The color of her eye with the blue/green and browns that work so well together is simply beautiful! Of course, the mascara helps everything "pop" as it adds contrast against the white of her eye and enlivens the entire photograph. We seldom get to see a human eye like we do here since it is larger than life size.
I have been a professional and fine art photographer for many years and have witnessed several technical breakthroughs in photography but some of the recent advancements in the tools available to us are incredible. It is not possible to see here what I see in the print. When I look at the photograph I keep thinking that at any moment she will blink.
