The point I'm trying to make is that we tend to amplify things when we're looking at the sculpt by itself, and not the finished figure. The squint, for example, is a common complaint, but I have to ask, is it because the eyes don't look like Eastwood's, or because they don't look like that picture? I mean, gido posted an image a few pages back of Eastwood, and the eyes look like the sculpts, but they aren't squinting quite as much as in the screencap you posted.
As I said, though, this is supposed to be a representation of both Eastwood and the character, so, there are trade-offs to ensure that balance is met. I'll be honest when I say that, front on, I agree with you that the bottom of the lip does seem a bit too full. Like everyone else, I saw the painted sculpt minutes before I posted them here, so, I didn't have much time to gather my thoughts, but, like I said, I do think that there are different factors, like lens distortion, lighting, and angles, and I'd like to see more of it painted before I come to any definite conclusions.
