Excellent shot Gaurawa! It's interesting that you were able to get this close with an ultra-wide angle lens. Didn't he mind you sitting on his shoulders? :D
My only nitpick is the composition. It's a little too tight on the left. I'd like to see a more space between the front tire and the left edge of the photo. However, with a shot framed this tight, that's a minor thing.
while this is an amazing shot, and will probably end up in the top ten, I don't know that it fits the theme as well as some other, maybe less intense shots. I do love the sparks off the wheel though... amazing. Have you seen these images? (Click on "Sandro")
