I'm trying to keep an open mind! I will say that the faces look better in-game than they do on the character select screen. It could be because of lighting. Also, the tweaks really do make them closer to the pre-6.0 originals. However, I think the problem with mine is that Helaani was created
after 6.0 launched, so
that was her "original" look in my mind.
I still prefer the 6.0 look for this particular character, but seeing the pre-6.0 against the 6.1 makes me feel better about it, at least.
Also, I must say that the human, gnome and dwarf females look so much better! The dwarf females don't look so tired anymore, and the human female eyes have some of their original feel. I still feel that the eyebrows are up too high, giving them a

expression, but it's still better. Sadly, my warrior, Daema, still needed a face change in the end. Even with the improvements, I don't feel like the new model captures her original look. I liked her narrow-eyed stern expression from before 6.0. The 6.1 version improved on the eyes, but I still feel like it's a little too smiley. The newer face is closer, but the eyes are still a little too large. But, overall, the model itself is a vast improvement, so at this point I'm kinda just nitpicking.

It's hard not to when we had a certain look for so many years!
Edit: It occurs to me that eye shape seems to be an issue for a lot of models. Before the re-vamps, characters had angled eyes, narrow eyes, heavily lashed eyes, etc. Now, it seems like they want to give every female these large, round eyes. The blood elf females are a perfect example. The originals have some pretty unique eye shapes, but the re-vamps gave them the same doe-eyed faces as all the other races (well, not ALL, but you know what I mean).
