here's what I would change

1.Make the man walk, not slide across the pavement
2.Have music to set the mood (intense, casual, etc.)
3.Give some background information on how exciting car spotting is as a hobby/job
(I really don't know what carspotting is other than photographing cars.)
4.Deform the "Nikon" text to make it look like it's on the camera strap (for the first couple times watching it, I thought that was a random label, and that "Nikon" was the guy's name)

Not to be a complete downer, you did a good job with the cars and the photo flash.
