Fireball Alchemy

A friend of mine, , asked if I could make them a wallpaper for their computer. I need the practise so I figured why not...

Anyways they wanted a black background with a flame or a fireball in the middle and the transmutation circle seen on Roy Mustang's gloves in the anime Full Metal Alchemist in the midle of the fire.

Im not too good at this sort of thing but I think it turned out pretty good, concidering im a beginner...
I used, , SithSpidey's fireball Tutorial, found here [link] to make the fireball.

Full size is 1600x900 so its pretty huge...

Any C&C would be great thanks.
