Cyclist racing down a descent

Took this pic of my brother on one evening in Kenya as he was riding.

Pleased with the result but upon looking back, I should have tried to

take the picture from a lower angle to provide more impact. Opinions?

Yes, a lower angle for the photographer and if possible leave a little space above his head.

If he rides this route routinely, you could watch how he moves and get really close (but not get in his way), looking up toward him as he comes down the steps.

I like the blur, it gives a sense of riding down the hill.

Great panning. Interesting lighting too. It seems to be from behind and low on the back of the riders leg, arm and butt however there is now shodows in front of the rider on the ground.

Was this because of a remote flash or just a fluke?

why is e in the middle of the frame? I think it'd be better if he were 'going somewhere'. Try placing the rider on the right side of the frame, give the cyclist a place to go.

Also, I'd like to see this either from higher up or lower to the ground.
