Great job panning .... I love doing these! I love doing these with the fast bikers going through the park. At first I used a triod, but found out that it's possible to do handholding. Love the car lights in this one of yours.
I like it alot, will have to try that. Plus it tells a story, looks like an accident about to happen the way the truck looks like it's speeding and the approaching car is not going to stop...
