Well, aside that I dislike the render itself, I suppose what you did was an enhancement of the fire effects - I'd like to see the original render to see exactly what have you done.
Otherwise, the composition is quite simple... I'd note the words on top aren't very easy to read - maybe because of the glow and the color of the font which are so close to that of the background.
The border you created kinda makes me a bit annoyed, or rather, the fact that most of the picture seems "bleached" while the border seems to be using the color the composition should be using. I'd suggest maybe a difference in the contrast level instead of lighting.
