The line art, really? You've finally completed your drawing, congratulations! I know, something that looks complex, can be...well complex! The trick is to take your time and keep practicing until you get it right. I guarantee if you master this drawing, you'll be able to draw your own type of skull. It happens to me all the time. Well peeps, I have to move onto my other tutorials now. Good luck, and most of all, have fun!
