I really dont see the issue. The hair on the model looks absolutely perfect.
What people forget about DBZ, is its a DRAWING. That means it can look infinitely different from any angle, because a 2 dimensional image is not bound by the rules of 3 dimensional space. Im willing to bet that if the hair texture had a few black lines on it instead of an orange gradient, ssjgoku god would have had nothing to say. You just dont have a case if you take the model from one angle, and compare it several images of the anime that lacks continuity at the best of times. If anything, ssjgoku gods mockup of images against the model demonstrate without a doubt what a fantastic job Doormat has done, not the opposite =S
Doormats model s**ts all over this one, and every ESF Gohan ssj2 ever made yet.
