First, I'd check out the agvis forums for help with VRay. It's full of tips and tricks from the pros. Second, I'd pop over to sketchupartists.org where you'll find tuts on creating this and many more effects, but not necessarily with Vray.
I've limited experience with Vray, I'm devoting my time to Twilight, but I'd imagine this imagine this image had lots of post production in an image editor.
Finally I'd post some pics here of your result/issues etc for some feedback from the gurus.
Thank you very much for your advice. I will look into this.
Will report back and share when I find out how this is done.
