mr. "scottimation" was right...a bunch of small triangle faces where the problem in my case too. Though, thanks allot for your support, from all of you. You are very nice guys and I am pleased to work in this kind of atmosphere with helping and encouragement.
Keep it up, because you will have to win allot.
So... my update... slow but I manage to achieve something.
I just jump back in forth, between 3dsmax and Zbrush and I work in the Lowest resolution possible to make the transition.
I work on the head mostly. I will probably make some sketches to further enhance the expression and feeling.
I need your support about this. Tell me What do you expect to see, like the best way to represent, an extremely dangerous expression from my model.
