Illustrator Name Tutorial

I did the smoke tutorial to create my name. It can be found on the following website: http://design.tutsplus.com/tutorials/how-to-create-smoky-brushes-and-type-in-illustrator-cs4--vector-3226.

The main thing I learned was how to create a smoke art brush. I feel as though I did a good job contrasting the size of the letters. I want to learn how to make the smoke look more realistic. I need to research different ways or patterns to follow with the art brush to make the smoke appear more life-like.
