Fright

I sorta like the background and the lightning, not feeling the colours in the middle(that part near the red gradient, looks like blue to me, it doesn't fit too well imo).
I don't like the render and the text you picked up mate, i'd try with different render (or no render at all) and replace the text with something minimal (century gothic/arial).
The bg is interesting i'd keep it and work some more with another render.
Hope it helps, i'm not good at advices ^_^
