Oh... finally you're getting a grasp at contrasts to give a more powerful impact. We can't see the rainbow lines, but it would be insanely cool to get a closer look at them.
Thanks, hope you like the black & white contrast. I was actually inspired to do this after seeing one of your backgrounds on your profile. Did you take that photo?
Haha no, I'm not that good. ;)
Do tell me where to find. :)
