Do you feel like the faces of human champions are incredibly off sometimes? Ahri's current splash art isn't Ahri (Dynasty also got butchered, and Popstar never looked like her), for example. Fiora (even though she's been updated, compare her face in her current splash art with her Pool Party one) isn't Fiora.
For such a large company, you'd assume they'd hire people who know how to draw a champion's face as it's supposed to be. And this bothers me a lot.
The Fiora difference is because everybody in the community bombarded Riot saying the default splash face is horrible, and Riot acknowledged this. So the new splashes don't have that face, however Riot refuses to change the original splash.
I give leeway on most faces because the two teams are different. Jhin's eye color is canonically blue, which is reflected in the model, but in the promotions and splash art he has red eyes due to a miscommunication.
There are other inconsistencies that bother me. In particular, Akali's splash is drew her hair incorrectly (it's a regular ponytail, but Akali ties her hair twice), and her front sash thing doesn't have the Fist of Shadow mark on it.
