Whoa! I certainly think you´re on the right track here, mate! (actually I knew it since the cranium change hehe)
... It has really improved a lot! I would be more carefull with the lips outline, it shows a somewhat of a smudge, might want to check it out.
I found this link in my Favorites folder, might help you out a bit with the hair (or even provide you with yet another way of making it)
PaintFX the ultimate hair designer
**edited** Yet another one --> Menithings Digital Hair
Hope it helps!
btw: I don´t actually like the first tutorial´s hair itself, but it shows a high degree of customizability so I pretty much suppose it could be shaped into anything you´d like.
