hmm I'll make what I think you had in mind and post it here and if you decide you want something added, I'll save the PSD so I can make quick changes just in case you dont feel its enough. ;)
Here is what I have so far, I made the render flame alittle darker yet brighter to give it more heat. I will tell you this was one of the most hardest renders I ever had to work with, when I saved it and opened it in photoshop it gave me a transparent background with just the flame, but when I saved it as a PNG it gave me the rest of the background, so to check how I was doing and how it looked I would have to save it over and over and upload it to my photobucket to look at how it turned out.
I saved the PSD, so if u want anything changed or anything added let me know. :P
