Thanks, guys. I currented V2, since that was my personal favorite of the two as well.
I'm not going to tut it, though. All I really did was paste the render on a plain color background, smudge it a little, then add a few C4Ds and fractals, blurred them a bit, and add contrast adjustment layers, gradient maps, and in the case of the blue one, a color balance adjustment layer. It wasn't that much, but I still liked the result.
