3 deviants said Yes, I want to see character's different clothing, expressions, postures!
1 deviant said Yes, I want to know more about characters, their personality and backstory!
No deviants said Okay, I want to see the art, but I don't read any text...

No deviants said No, I think they're just a tool for artist himself, pretty much like script, and author shouldn't upload them.
