I hadn't really thought about it before but I realized that is a bit annoying once you notice it. Kind of like when you notice an anime character's hair parts but has no canon direction because it's constantly flipped to be convenient for the scene.
For one of my future projects, I have a character with a tattoo sleeve. My intention is to draw her sprites normally, then have a second flipped set on which I move the tattoos to the other side, ensuring no matter which way she faces, her tattoos stay on her right arm.

I consider it extra polish though, so I don't think I would think less of a game for having a minor annoyance like moving tattoos. It seems nitpicky to me to mention such a minor factor in a negative review for a VN when it's such common practice to just flip sprites without editing.
So I thought I'd ask on here. How much does a game noticeable sprite flips matter to you? Does it bug you when things don't stay consistent or do you just not care? Would you bother to have edited sprites for facing the other direction if it were very noticeable on your character like if they had a missing eye or a special marking on just one side?
