Powerful Background - GraphicRiver | 58 MB REUPLOADED!
High resolution background set 3000×2250 @ 300DPI
Included are 4 color variation backgrounds, a layered PSD file for full editability and the original lightning and flare PNG files.
I have set up several master layers to affect the overall color of the design.
There are lots of layers to experiment with to create new looks, try simply turning the visibility of layers off to produce new looks..
