Just my opinion from Lore. Artistic licence and all that.

Elves - way too tall and stocky, facially idiotic, look more human than human.
Half Elves - Too tall, facially no different from humans or elves which looks odd.
Halflings - Seem okay apart from too stocky, feet too small and giant heads. They look like they would need to use their legs to push their head though the dirt.
Dwarves - Pretty good.
Humans - facially (female especially) look like they have extra chromosomes.
Githyanki - Mmmmm okay but more alien body types from what I remember, closer to humanoid insects than mammals.
Tieflings - Tieflings are humans with horns basically. Horny bastards, can see Larian put alot of work into them.

Pretty sure I have seen a similar thread BUT Iooked though 70% of the 1300 topics to bump it and never found it. In my opinion it is an important topic from a lore standpoint, attention to detail required.
