Sorry for this kind of belated update. I'm currently dealing with some time consuming family-related stuff, so rpg-o-mania suffers from lack of free time.
That's what happens when you're doing things mostly alone :)
But today, while I waiting for some stuff I needed, I was able to remove the background from some nice Final Fantasy art. It's from Final Fantasy V and VIII, but the art itself is from "Brave Exvius War of the Visions".
Anyway, the nice artwork is here.
