I like the choice to flatten the tones. It helps to merge the human element and the water as one. Overall, a very captivating image and as a result, the YankO Red.
This is my favorite of the 'person in water' shots. I like the way the DOF blurs out her body to contrast the dark water. It almost makes her head look disembodied, which creeps my wife out but I like it.
8 - Nice eye contact/capture - sets this apart from the other similar styles in this Challenge - gives the image a 'pure' feel, without invoking 'negative' thoughts.
