Nice.. it looks like it's in the 60's!
Stunning pic. Makes the car look dark and evil. And kinda scary with the light reflecting off the paintwork.
Its a flourescent lighting filter if Im correct. But I could be wrong. All it does is make the white light glow more. Along with the dark eerie colour tone I would assume he used a drawing filter. Something like "Dark lines" and then perhaps used the history brush to make the picture look real and not all photoshoppy like.
