Exorcist Teacher volume3 cover: Zombie Creator

The colors, concept and exposition look amazing as always, there are a few things that catch my eye upon looking closer, though. It's nothing too big, but it's something on a base level, like for example, I understand that they are looking up, the two women on the right, but somehow it feels like they have their eyes wide open. I am no artist but I think there should be something there... Maybe a little bit of a darker line for the lower eyelid, or it being a bit wider?

The other minor thing that looks confusing is the left shoulder of the girl in the bottom right. That is not how a shoulder looks like, I was looking at it for a while, and it doesn't seem like it's something else, but there shouldn't be a joint there. The shades form a shape, that... well, shouldn't be there. I'm not familiar with the character, but she looks human, and there's already been space allocated for her shoulder a bit higher (the curve on her top clothing piece). That exposed arm just doesn't seem right to me.

I'm no artist, and I am not familiar with the characters. I might be wrong, but as a person who loves art, those are my thoughts.
