Aranthys -> I disagree on the hair. Indeed, Arta's other Edwins are fine, but here we try to present portraits that are at least a bit closer to the FR Lore and Red Wizard shave their heads + have tattoos. I have nothing against adding a hood (if Arta feels like working on it) and as long as it's fine to have "hairy alternate", I would rather his present portrait stay as the main one. Also Rashemi would rather avoid tattoos, due to the conflict with Thay. It is said that some noble Rashemi can have "mulan tattoos", but I don't think Minsc is like that.
Dorn and Rasaad were done before the release of EE so we could do nothing, but guess NPCs' character.
