Not sure about the blurred lower body - seems incongruous with the in focus upper body, when it would be basically on the same plane. I see what you were aiming for with the foot in focus, but the blur seems contrived.
the selective blur doesn't make sense to me, how can the foot be in focus when the legs aren't?
Besides that, "Karate" doesn't fit my definition of "Games"
Unfortunately, this doesn't really meet the challenge for me. Interesting shot, but the blur ruins it for me. My brain is telling me there's something wrong when her foot and head are both in focus, but her leg and body are not.
