a much, much tighter crop could have made a couple points difference in your score. you could have come down on the right guy's head and all the way over to the fence post from the left and have had a much different image.
Ok. Except for the flying dust, I do not see any thing that causes a great impact in this picture. Would have helped if one of the two had their face towards the lens... or perhaps a different angle would have helped. As it is, I rate it a 6/10.
