Arnit, this is my favourite of this challenge. I was a bit surprised that this photo was yours. But now I have even more respect for you because I see that you not only can make good photos with a "nice" theme but also about a more dark theme. The lighting is so great and focus, too.
I don't mind your mock suicide here (I hope it was mock!), and the use of depth of field is pretty good, though sharpest focus is on the fingernails, and I'm not sure why fingernails are important here.
i think this could have been a really powerful picture if we were able to see a little more of the person in the background (like maybe a spot light on her eyes).
