art / gfx Spectrum

[Chaozzz]

Here's a new piece I made. I want to add more to it, but I can't think of what else I can add. It needs to be something subtle. I tried doing a Gaussian Blur type Vignette effect but it didn't look like how I wanted it to look.

 

It's called Spectrum. It's a variation of a tutorial I found. I can look for the tutorial again if anyone would like it. I did this in about 2 hours all in Photoshop CS4.
