I LOVE photos like this because they suggest an entire mystery story. You've called it a murder. The girl is anonymous; we cannot see her face. all we know is at the moment of death her innocent bare feet came to pointe like a beautiful dancer.
Quite interesting. While somehow I don't think this shot reaches excellence, it is one that sticks out above the rest of your work. Points for the concept, and even more points for the excellent crop, but the colors, backdrop, and wardrobe somehow don't complement the shot.
I think this could be re-shot better...but this one as it is certainly isnt bad .
