Dangerously Beautiful...

Here is my finished piece. Decided to draw this chick with my new pencil I just bought to give it a try. Not very happy with her hair at all, I really hate it. Anywho, tips and pointers about drawing hair would really be appreciated. Really like the shading, but then again it's just me. Hope you enjoy it. Was really surprised as too how fast I drew her and shaded her in. Really hate my laptop right now. I apologize for the uglyness of the photo, but i'm stuck with this crappy laptop till I get a new one in a few months. Comments are awsomely appreciated as always... tehe ^^ Enjoy...
