Ah, I'm definitely not saying these aren't good - they're far better than anything I can come up with, 'fo sho. I think it's just a minor stylistic preference of mine. On some of my female sims, there's a noticeable dark stroke above the tearduct. It actually looks great on some sims, but on certain ladies with particular facial characteristics (deeper nose bridges, different eye apexes, etc.) the stroke looks sort of out of place.

It's less noticeable in certain lighting than others, though. Not really a big deal, but I guess I just have the 'perfectionist' trait. :P
