Take your pick Calintz! You know that list of configurable options for graphics at the end of the config section? The goal is to use as many of those as possible:
Action, skill, item, idle, and charge sprites for actors and enemies
weapon sprites (LB is doing these)
Running, sneaking, and jumping sprites (for party members)
Level up, flee, call for help, defend, and Unsummon animations as well.
Take your pick!
