Man OP is really clear and honestly this gets +1 from me.
But question regarding half-orcs.How human should they look like? Like is it supposed to be closer to the various fan arts where they look like buff green elves or are they supposed to look like the unholy monstrosities from the Elder Scrolls Oblivion?
They're not supposed to look green at all for starters. Faerun orcs are grey and half-orcs are also grey or just really pale. And if Larian are going to follow their traditional depiction, then we should expect bulky grey-skinned humans with flat noses, slightly pointy ears and variety of fangs.
