Sorry, but this just looks like a bad snapshot. To be effective, this sort of shot needs to have something in focus. The red hat guy's face would be a good focus point.
I've given the same basic comment on quite a few shots -- my preference (as I discovered while looking at a number of these blur shots) is for a sharp subject. When there is no sharp subject, my eye wanders around trying to find something to focus on. That really happens on this shot. Perhaps just a difference in artistic preference.
