I have one suggestion to kinda help the bland the color of the bg, take the render copy it and motion blur it like mad and then gaussian blur 20 px or so and resize it til it fits the whole sig and then overlay it and adjust the opacity as needed that should help you out
A little grainy, but it's a really decent tag. Good compo, and nice flow. Like the colors as well. Lighting looks good to me. ^_^ I personally think it could use some more C4dage. But it's still nice. Good wrok
