I would like to affirm what Frank (PhotosGuy) had to say. In the first shot, I would like to have seen his face - something to connect me with the photo. The only times I find an image that works when the subject is looking away from me is when (s)he is looking at something in the photograph that is compelling. In this case he is looking more or less down the street at basically nothing.
On the second shot the action is good - clearly the subject is in motion so the shot is dynamic, but the fingers hitting the frame kind of sour it. If the frame did not have so much space in it - a much tighter crop - then there would be a reason for the fingers hitting the frame. Try a vertical 5:4 crop, starting in your current upper right corner and just including the foot. That might work a little better. Besides, most everything on the left half of the frame is not contributing a lot to the shot.
