I would guess that the lines and stuff in the background is either c4d abstract renders or effects, and then they and Venom has been smoothen out with the ps plugin Topaz Clean► http://www.topazlabs.com/clean/

It's pretty simple, add some c4d's in the background, add Venom, play with the color adjustments and then finish it with Topaz Clean.

The Venom render is cut by me, so if you want it I can link it to you
