Tim, after going through just a few of your tutorials on natural phenomena, I am beginning to see a greater awareness growing within as to how I might apply your use of Blending Layers, styles and photoshop built in filters in ways I had not even considered before.
Your book, easy to follow, doesn't over complicate things, and area that I had never explored, or considered useless for my needs when using photoshop, are becoming an intricate part of my creative daily work flow.
Thank you for opening my eyes and mind to the unexplored world of photoshop.
Cheers!

P.S. Here is a sample I created using your fire tutorial and one of my own pictures.


I've attached another image as well.
