The art is just rpg maker assests mixed around. I'm not terribly good at asset creation and not really interested so i have no shame in buying assets to use or using freebie assests. I do like to figit with them though to see what they look like in various nonstandard ways.
An example is the spell animations, a lot of what i've seen with rpg maker is people either use the default animations in intended ways or try to make their own assests for anything non combat. I think a lot of them look cool and could be used in many noncombat ways. The tornado animation, for example, can be used outside of combat in combination with jump animations to look like its flinging people or whipping them around.
