I have a theory why that is. Main scenes are reserved for Siserg (Head artist) who is also working on another game called Souper game. Figurine art like Hermoine on the bed is done by other artists who focus on lesser artwork tasks like drawing potion bottles, hair tuffs, etc. Basically icons for interactable items from your bag. That's my theory. As long as the main scenes stay with Siserg we should have art consistency.
