This model is just wrong . , how about trying www.3dtotal.com , load of tutorials for max , use the joan of aracdia tutorial , this guy shows how to model a head with perfect anatomy step by step .
The tutorial that u use is high poly modeling using curves , if you want to model a low poly head you should stay off this tutorial , and i always recomend to go on poly modeling first , so like i said joan of arc , ive started with this tutorial two and a half years ago , and this was my first step into the world of 3d modeling , hope it will work for you too . o and try cheacking my last head model , it was a few months ago but with a perfect anatomy
