in Pillars of Eternity, we get our portrait shown when we were "thinking", it's a monologue, so it makes sense.
unlike in UnderRail where we never think, our thoughts are presented in narrations like i said before.
and in that game, our portrait do not show up when we choose a reply while conversing with an NPC, same thing happen in UnderRail.
Original Sin 2, now that's different, we get to see our portrait when we're making a choice for a reply.
speaking of little detail, i really hope Styg could add some voices for combat instead, like "Aargh!" if someone is being hit, or "Whaaaa...!!" if someone is set on fire, or "Hurrrr..." if someone is hit with electricity, or "Brrrrrr..." if someone is hit with frost. it's also a minor thing, trust me. even Styg can record his own or his female friends' voice for that kind of thing.
