There are loads of visual artists with a long history in drawing and designing fantasy characters that could do a much better job of making the character models and appearances than Larian seem to be, this is evident in the fact that even most indie games have much nicer looking characters, as well as just about anything you can find on Deviant Art, also many games with all their community made mods and additional characters, but still a supposedly AAA game studio that charges $60 for their game still can't hire one?
The heads are all 3D scans of real people. They've just been modified to look more like the other D&D races. You can see the same of the same scans that were used for humans were used for other races.
And this is exactly what the problem is. Nobody asked for this and very evidently, it works very poorly. The characters look terrible.
