Program Nami's head does not hold up to the splash.
As a Nami main and a member of PBE, I really don't like the Nami skin. The chromas don't change the color of her abilities to whatever color her tail is, but they otherwise soften how terrible this skin looks to me. It's the head and the hair I think. They need to do something to make them look more like the splash. The hair looks terrible in game. The in-game view that you get of Nami has the "hair" spread apart -all the time-. So rather than looking like "predator dreads" or like they belong (like the splash art) they look... awkward. I don't know if there needs to be more of them or a different motion of them or spacing of them. I also think perhaps the white piece on her forehead could be too large. I don't know what makes it look like this, but it doesn't look right.
I'm no one, but I'm not happy with the skin. I don't think my opinion matters that much, but maybe others agree with me and will also voice their opinions to Riot. (They may have already done so, I only scanned the first page of this looking for Program Nami comments.)
