thanks for all the comments, much appreciated!
The lighting setup is -
4xElemental B-series heads, main light with 40 inch reflective (silver) brolly, second fill/hair light with small softbox.
6x7' Lastolite hilite + vinyl train, one light inside the other aimed at the join with the floor directed using honeycomb and barn doors. I have a Sekonic 308s that I use for metering which makes life a lot easier!
All shot with D700 + either Sigma 50mm f/1.4 or Nikon 85mm f/1.8 at f10.
