Wow, the graphical style is very inconsistent! You could at least replace that RTP backdrop with a different one that's relevant to the area the characters are in. That way, there isn't as much eyesore in your battles.
By that, I mean that you should do make a new map, place an invisible hero in it, testplay it, printscreen it, then paste it onto any image program you want (just don't optimize it in MS Paint, though; it seriously screws up the colors!).
