>>10448556>is cell shaded looking bad on a figure?It depends, some people love it, personally my issue is that it makes it so that shading is only coming from one area of a figure. So the lighting is locked in one position, which I don't personally like on an articulated figure.
>how would this improve his wrinkle details.Basically, black is a very flat color and it looks less organic in real life. while it can help push the animated look, in most cases it's preferable to shade with a darker line in the same color range as skin(i.e. light/tan flesh becomes a deep red/brown color instead of black)
You've probably seen old pics of gundam model kits with heavily blacked out lines; that was sort of the amateur way to do it in the 90s/early 2000's, since then it's more widely known to panel line with gray because it looks more natural and effectively works as black, but more fitting in real life and not as flattening.
