Hi and welcome to this excellent community!
More than feedback I would like give you a few tips, always try to use a unified color palette depends what are you trying to show (magic, fire, ice, etc) just type in google what color palette would you like to use and you will find unlimited options to choose for.(Ex. “Color palette cold”)
The second but I believe the must important point above the others, “times”, this is need it to transmit what would you like to, an huge hit or a burst of magic dust. A correct timing can transmit a correct energy hitting a heavy weapon, shooting magic missiles or just casting a powerful shock wave
I hope this tips will help you at your futures fxs
PS.: sorry for my english
