Thanks to all for the kind words.
I'll do one from behind tonight, I'm super serial.
Trying to remember what I did for the hair, it was almost entirely done with a 20 year old pot of citadel's 'blazing orange'.
-If I remember correctly, I drybrushed white over a black undercoat first.
-Then lay down several thin layers of blazing orange, really watered down, until I was happy with the darkest areas of the hair.
-There should be some shading apparent as the white and black areas show up under the thin layer of paint.
-Then I picked out individual streaks of hair with blazing orange, simply appling the paint thicker to areas I wanted to be brighter/lighter.
I was suprised at how red the finished hair looks but I guess that is from the black undercoat darkening the orange so much.
Edit: At some point I painted a very watered down layer of black over the hair to smooth the transition between light/dark areas, but I can remember when!
