If you give my supposed 'more youthful'-character a far too profound nasolabial folds on his face, then having good or bad lighting won't matter. He's practically 15-20 years older to the future---he's not 'youthful' anymore.

If you keep my 'more youthful'-character they way he is, then he'll still the 'more youthful'-character that I recognize & love. Bad lighting won't make him look old, not in the drastical way that those profound nasolabial folds would give.

Big difference.
