Three words,
crop and re-position
The kid and the skateboard are very small in the frame and get lost in everything around him. Also. you have him moving right to left and to the left of the center of the image. That makes his movement carry him right outside the frame. Also, placing the subject directly in the middle of the frame on a shot like this this makes the image look very amateurish and snapshot-ish in my opinion. Although it cannot be fixed without re-working the image in Photoshop, you need much less depth of field to separate the subject from the background. Granted, on DX cameras with their tiny sensors and shorter focal length lenses does makes this more difficult. It is better to open up and manually zone focus to get that shallower depth of field
Crop the image and place the center of his face closer to the intersection of the RIGHT VERTICAL AND UPPER HORIZONTAL THIRD of the cropped image with his direction of movement going INTO the center of the frame, rather than out of it. Also, the image is a little dull and flat contrast wise. It needs to be lightened a bit and more contrast added. One of the things you have to deal with shooting on an overcast day.
