I actually really like this head, I love realism and mech's and lensflares, while this one is simple and I'am not a fan of simple things, this just looks cool.
Maybe it's because it looks like vector graphics a lot.
I think this head will go fast for 3000TC on the market, it is attractive, simple and nice. There is no changes to be done to it in my opinion.
The style from which your head was made reminds me of so many others my head hurts
but all in all it is ok, I wish there just werent so many regular shapes since your going for a realistic type
Is this a finished head texture? if so, then how much does this cost?
