Over blurry. Some blur can enhance an image, but if you overdo it it takes away from the image. Thats exactly what we have here....but I'm sure you've had alot of similar comments by now!
This shot would have been really great if the background were in focus, i.e. only the players were blurred... as it is, it looks more accidental than planned, imo
Good dynamics here.. The players remain recognizable, as well as what they are doing, and you get a good sense of abstract as well. I'd have also loved to have seen a shot with maybe only 3 of the players.. (or even two), with some larger dimensions.. something approaching 640x500 maybe.
