Thanks for the kind comments - i think it came out alright, i would have liked to add a lot more detail and fine tune things, but as it is my computer had already slowed down dramatically, where it was becoming difficult to work - this mainly because of the hires textures and the 4 particle systems.
Yes, the hair was one of the main focus points for me in this render - i had found a new node setup for hair that i loved and thought i would try, and it shows slightly in this render, but its true potential would have to be a close up render - the node setup allows one to control darkness at the roots even the length of the darkness, then there is a Voronoi texture mixed in with the colour of the hair giving different shades of the same colour to strands... over all the best looking hair (my opinion) that i have seen.
