Thanks! All the objects in the scene have the standard vray optimized shader. I used Vray's distributed rendering system to render the image on 3 computers at once. A total number of 10 processor cores worked on this for 7 hours.
Oh yea, sculpting with a tablet makes things easier but opens up a lot more possibilities, I cant see myself sculpting without one. Its like drawing in 3d. Cool, good to know about the lights if I ever try out vray, thanks.
