¡Bravo! ¡Magnífico! It is an incredible work! I've always wanted to draw these tiles for my game, but I do not know how. In any case I'm glad to finally see a Final Fantasy in RPG Maker VX Ace. My language is Spanish, but I'll play this game even if it's in English. It look's great!
P.D.: One last thing. Could you tell me how you managed to extract these graphics? I always wanted to get my hands on them, but never found them.
