This image is very compelling and wonderfully rendered. As many commenters have said, it's superb photojournalism. I can not believe it didn't finish in the top 10 - or even with a ribbon.
Please disregard the comments that implied you were "lucky" getting the shot. I personally believe we make our own luck in most photo endeavors. You were there, you had your camera, and you reacted quickly enough to capture a perfect story in the making.
The image holds key elements, such as the gloves on both hands, the shape in the car, the position of his feet, and the pose itself.
Exposure wise - it's right on. The huge contrast between the dark black smoke and the orange flames is really dynamite.
My only suggestions for improvement would remove the "centered" aspect so it would not fit the challenge as well, if at all. That suggestion would be to move the camera to the right a bit - so the the rest of the care would be shown.
Overall - great seeing and reaction, congratulations.
Wow - is that dynamic! Great capture. Did you notice that the silhouette of the bucket has a fire pattern behind it that makes it look as if the bucket itself was on fire? Is that shape in the car a human head? If this doesn't finish very high, I'll be very shocked.
