Little abstract wallpaper, need advice for it

Just a little thing i whipped up in about 20 minutes, i need some advice on how i can make the render look a bit nicer.

Currently it’s 1366x768 (my desktop)

Render settings are Default with the exception of Indirect Lighting.

I can upload the blender file for anyone who wants it, but really just looking for some feedback or ideas.

I like where you are going with this. But I don’t care for the plain gradient that takes up the entire left side of the image. Perhaps add some dark textured background to go along with the gradient, or even perhaps another subject to share the focus with the light.

It’s a cool start, I like the trail thingys from the light.

Perhaps, the dark area around it could be a dark cave with very little of it illuminated by the abstract light. Give it a sense of mystery.
