Sweetpea's Glasses removal can be considered a stylistic change, but it's still inconsistent. To suddenly have her glasses removed in the second scene without a mention. Why not just remove the glasses altogether in both images?

For Gentian, you can't even consider it a stylistic change. Without the change in expression in her face, it's literally just the same as her first image, but with photoshopped white fluid. There's no reason to not implement her second image into the Nutaku version, unless they have some other bizarre reasoning as they did for swordhilts and blood.

We can speculate all day, but you may as well just bring it up with Nameless and see if he can look into it.

(They need to fix Asagao first though.)
