Hugh Laurie is such a great actor! And I just loooove House MD

Allright, I've spend quite a long time on this drawing so far, but I've really enjoyed working at it! I've been drawing while watching the series in the background and drinking pepsi max xD Things can't get any better!

Of course I'm planning to finish this drawing, but I'm worried about ruining it, because my hairdrawing skills is nonexisting xD

Has anyone got any advice on drawing hair (or even better, a good tutorial)? And wish me luck
