Background??

I need some kind of background to fill this signature :) Anyone got any suggestions?

maybe instead of making the effects black should make them a light blue like lightning make it stand out more .;

Space nebula, it's pretty overused but it might suit it.

Changed it only slightly, without adding the background .. What you think?

Cyan brushing set layer to colour dodge. Put texture on top set to overlay.
