What my question is: How did he get the stars to turn out so well with so much light pollution in the foreground. I'd love to hear about that.

I'm no photography expert but I believe they used a timed flash to freeze the rider in the shot. Basically in low light situations they by leaving the shutter open it allows more light to hit the "film" aka sensor. The sudden flash of light causes the rider to become more exposed at that moment than he is at any given moment which in effect freezes him. If you look in the lower right corner you can see the rest of the flash. I've never used this technique though so correct me if I'm wrong.

No. The giant S on the bottom bracket stands for Sunshine.

it's kinda hard to catch, but actually to the bottom left is the out of focus foreground, which gives away to the jumps in the middle ground which are in focus, and jumps back to the out of focus trees in the background. That may be one of the thirds Ian's talking about.. another thing I see is the use of the the golden number..(Ian actually gives a more detailed description of it in his tutorial on composition), but the foreground and middle ground divide the the photo in half, and then the rider being positioned to the left of the upper half divides the upper half again. Also maybe the fact that the riders line of path, and the jump are criss-crossing with the multiple lines of tape dividing the shot into thirds where those lines cross.. But Those lines seemed bunched so that may be a weak argument. Just how I broke down the photo anyway.
