This is what I thought might be the reason initially....but with the Dwarven, Gnomish, and in particular the Gith faces, Larians seems certainly able and willing to tweak the face scans to get them 'right'. So the usage of face scans seemingly unaltered (save for the ears) to use for elves is a bit of a mystery. My only speculation I have for them is that they don't think people would be as receptive to 'alien' looking elves and so decided to go with more conventionally-attractive looking head models.
As for the larger discussion on how good Larian's character creation is....I think It's *OK*. Elves get screwed again with hair options since almost all of them clip with their ears, 2 voices of each type is really unfortunate, and I hope it's not because they are planning to make 'Tav' voiced. Piercings should be available to everyone instead of limited to a specific subclass, etc.
I think it seems underwhelming because of the focus on cinematic up close shots and animated cutscenes etc. The limitations in character creation there make what would otherwise be pretty good look....not so pretty good.
Particularly, I meant that within a specific race, many of the heads are duplicates with minor modifications. Some heads may also be shared across races, but I don't remember that so much. But with the exception of Gith, even the racial modifications to the human face scans are not particularly extreme.
But that wasn't really the point I was making. I LIKE the face quality, and I don't want elves to look other-worldly ( I don't even like the current ridiculously pointed ears; the D&D elves were originally only slightly pointy-eared ). What I was illustrating is that using face-scans reduces the ability to customise the face shape to approximately zero. In EA, this usually means you only get about 3 genuinely distinct head choices for any given race/gender combintaion.
It's a technology choice Larian made that has obvious consequences, both good and bad.
