These are just some sprite edits I made for fun. I think they're neat, but that's just me.
Top left to right: Lightning, edited from FFVI's Celes; Sazh, edited from FFV's Galuf; Snow, edited from FFVI's Locke
Bottom: Hope, edited (rather poorly) from FFV's Bartz, Vanille, edited (also rather poorly) from FFIV: The After Years' Porom, and Fang, edited from FFII (Dawn of Souls version)'s Maria.

The Final Fantasy series and every game in it belongs to Square Enix.
