NPC characters (especially major ones) are full of details & unique traits indicative of their actual characterization. For examples:
+ Having character like Judy or Kerry littered with tattoos that blend naturally so well with skins, like actual tattoo colors that looks like years old age are very meticulous & know what tattoos actually looks IRL. Not includuing the many kind of symbolism in it. Not even most movies done this kind of things right btw hehe
+ the textures for fabrics of clothes in this games are very realistic imo. Also the actual fashion clothing that I think legit grounded & could be very much a thing IRL
+ little details of movements in animations like someone is groggy or suspicious or in-disbelief or confused or holding out anger etc. Player can see this "micro-expressions" of body language in a full blown heavy dialogues open world RPG game.
+ makeup shapes & colors in this game actually looks like a proper makeup LOL
+ details on weapons in this game also amazing, up there with some proper FPS focus AAA games.
