One thing that I don't think anyone has pointed out directly is that several faces have a dark shadow underneath their eyes hear the nose now that doesn't go away in pretty much any lighting (though darker, more contrasted areas make it worse). This is definitely due to the more prominent eyebags along with the harsher lighting, but I figured it might be helpful to point out. This really seems to me like an actually unintended consequence of the new lighting and models rather than an artistic choice. I've seen it on several different faces so it seems to be a fairly universal issue.
