Overall this image is a little flat for me. I like the concept and it fits the challenge but it feels just a little too close. Your hand is just a bit soft and if you had "stepped back" a matter of a few inches it might have given the image a little more strength. I admire the DOF though as the impression the image gives is that you were juggling the camera in your right hand and shooting at your left. Perhaps some of that "struggle" could have been used for a bit of intensity for the image as you include more of the hand and sharpen the action just a bit with a different use of light. Thanks for the image.
You did capture action, and it is technically pretty good (focus, DOF, but lighting could be a little more imaginative) but it's not much to look at, not that interesting.
