Okay, so I want to be clear that these are my opinions and ultimately they should not decided anything for you but inform!
Alright, I'll break it down by type:
Maps:
-The interiors of your buildings are big but not filled. I gather that you are trying to convey size, but Size is relative to the initial scale you set. The worst offender of this is the port building. It's a whole lot of nothing, that requires too much running around to even talk to people
-For the snow textures in town, the white square/green square is pretty noticable. There are most likely free assets you can download for blending snow and grass. Look into RPGM support sites
Gameplay:
-if you are going to make the characters comment on strength of the main character, make that evident in the way they play. Have Warren hit harder and Aurura weaker. Also she was hit and recieved zero damage, make it more apparent the difference betweent these two.
-Your characters are way to zoomed in when they are talking. I think you would benefit from descaling the image and then centering them. Koikatsu models don't look as good if they are constantly up close.
Scenes and Characters (This one is very subjective):
-Try to line up your backgrounds better, I forget the exact instance but you jumped from multiple different locations in the same set of story beats.
-Your characters have wildly varying face types. I want to be clear that im not saying variety is bad, but try to standarize things like eye size, face component positions, etc. Purple hair girl (forget her name) is the worst offender of this since without bangs it really shows the difference.
-orange hair's eyes have no highlights, which is normally used to show someone else has control over them. I would save no highlight eyes for when warren is doing his seduction on them, or when they are becoming corrupted.
-Aura's skirt is going through her shirt. This is your first character the player is introduced to, and it's a good idea to make sure that it looks high-quality from the start.
