I know Dawn has a tutorial on how to draw fire, but how about a lesson that teaches you "how to draw smoke" to go with the fire. Draw all kinds of elements only makes you a better artist. Which is why drawing wind, rain, sleet, and snow, is something that may sound ridiculous, but in the end that very skill, will help you draw your scenes a whole lot better. This is a linked tutorial that I think you guys will enjoy. When you are done you can customize your finished product after you get done drawing smoke.
