When there is a directional or moving subject like this. I like to see more room in front of them, and less behind. In other words, I would crop a bit off of the left side.
Normally, I agree. I'm not quite sure why, but I think it works great having him off to the right in this case--maybe even a little more than he is. Just my opinion of course, but I think it works well here.
i like it just as it is, makes it a litle more dramatic like maybye it was a hotter than normal day and him being more on the right makes it sem that hes a fast runner!!! just my 2 cents
