Do you know Starcraft2 a over 10 year old RTS game?
The portraits are animated. Every Portrait is a real 3D Head with Animations in a Box.
I am sure you can come up with a plethera of features others game have that, that others don't. Animated portraits for units, are a really, really small detail.
That said, when Starcraft2 was released, that was precisely what I was thinking - how cool it would be if someone did isometric RPG, and put that much production value into the game. I imagined Minsc, Aerie animated portraits on the right, and thought it would be very cool.
I for one think, that istead of doing a dodgy cinematic dialogue, Larian would invest into prytting up conversation box, perhaps with animated portraits like you suggest and maybe expad top down animations for dialogues, the game as a whole would look more premium that it will as it is. Cinematics of Baldur's Gate3 will always be stacked against Red Deads, Mass Effects and Witchers and with it's systemic freedom and customisable characters it will never come even close to this quality.
