These Legitimately look like they're from different games
Usually I think the splashes in this game are gorgeous, but this new Nami splash... I don't know, man. It doesn't look like Nami, and it's not nearly as rendered as splashes in this game usually are? Compare the Nami splash to the Morgana splash.

Nami's looks like a Smite splash compared to Morg's. Morgana's skin texture, the patterns on her clothes, the lighting on her hair - all of it is way more detailed and looks like modern League of Legends art. Nami's just doesn't. There isn't enough texture, her entire face looks off, her fingers are too long.
I realize these are different artists, and Nami's is going for a softer atmosphere, but games need to have cohesive splashes, at least when they're from the same skin line.
