You don't get it Scooby don't you? While you altered your GOW picture to make it more realistic - the Otacon model was practically unaltered with only the face being sticked into a photo with a similar bland lighting condition. The point wasn't to show that GOW can look better when you alter the colours - the point was, I believe, to counter the point that GOW looks more realistic. It doesn't - no matter how many people you ask, it's just not true. It looks much more CGI, that much should be obvious even to you. Does that make it less impressive? Hell no, but it doesn't make it look more realistic either.
You can't argue art-direction.
