Just wanted to make a post showing how the characters will have different facial expressions based on the dialogue. This was a concern mentioned in some of the new character art because the face in the new art is different from the old art. I assume this is a concern because in UMCH for example, the faces do not change. However in games such as Umichan Sentoryu and hopefully other future stuff, the faces will change based on dialogue and current situations like many modern VN type games.
Below is an example of various faces used for some of the updated character art.
some of these may need editing.
