Fire in Photoshop

My first project for Project Spectrum Elements is done, yeah! It was not on my yesterday's list, but has been in my head.
It went much faster than I thought thanks to a very easy tutorial.

The picture in the letters is from the most spectacular sunrise I ever experienced in the mountains of the Anti-Atlas in Marokko.
The fire and the heat we definitely appreciated because the night has been shivering cold.
