Beautiful, you've got the shutter speed bang on spot!

One suggestion though, it would have been more cool to have the tip of the sparkler burning. I guess by the time you focussed on the sparkler, it was already half way through.
 

Yup Nilesh, it was a very short sparkler and we didn't bought many :)
 

Very nice...sharply in focus which is very important...and Also a very happy diwali to you !!
 

Awesome pic :-)
