Ahhh the Topology
 

So here is the break down been trying to do a realistic human head for the first time with many ending in failure. The problem.... yeah thats right im not to good on the old topology. And with some helpful advice from Arran and some other faithful users i have re-attempted with the help of one of simply maya's tutorials the ninja dude. So my modelling method is nurbs to poly then to sub d for added tweaking. However I thought i would post where im up to now, which is right before i have to do the changes to topology and get everyones input. For example making sure the geo isn't to heavy yada yada yada...
