Hey Ashizian! You can check the asset priority lists at this link even if you are not a Patron.

There are 4 tabs, Theme tab refers to the next main asset pack release (for this month it will be Minifantasy - Necropolis). The other three tabs (icons, pack features and creatures) are the priority lists for the Patreon-exclusive sprites.
