Good way to capture someone staying still for half of a long exposure. The streking lights take away from this shot a bit, other than that it's a nicely balanced shot.
idea is neat. the photo needs a little more refinement, imo, such as a more pleasing background? if the rider is not related to you. then, I'd say it is a great capture. we all have to live with what we got. however, if he is your friend, i really wish to see a better background and set up etc.
