The ranking sytem seems to me the system to impress your emotions in digits.
10 of 10 must be absolutely perfect, right? In that case, im not sure i have ever seen any textures like 10\10 or even 9\10.
Always when i look at textures, in my head appears the words like: Cool, nice, shit, freaky shit, or nothing. I remember it was like OMFG ITS INCREDIBLE, but i rated it 9\10. The question is: What should i see and what should my thoughts and feelings be to rate it like 10\10?
About the head:
Id like you to know that human's eye cannot ever see true black color. Even when you are closed in dark room with no lights and windows with your eyes closed, you still dont see black colour like 0 0 0 RGB. And using that black colour can ruin your work. I cant understand what's in the visor's glass. The gas mask dont have that much volume as every other part does. It looks like its underneath everything else. It also would be nice if you fill that white gap with something.
