HELP: Seeking Sprite Update Mod

Around March every year I replay my favorite game, Final Fantasy 6. I've always been curious to play the game with swapped out sprites, and I'm going to give it a go this time around. If possible, I'd like a sprite mod that's based off of Amano's character artwork. I've searched around, but I've met with some confusion and I'm honestly lost with where to find this or how to implement it. Any help would be greatly appreciated.
