I don't even know if the artwork was uploaded to this site, since Josan12 and Jotsz sent me that work directly. Well, if the artwork was uploaded here, you can get your hands on that. However, you will need to modify the party NPC scripts in order to get them to actually use the new artwork. I can't recall if the NPC armor mod was ever released as a standalone... though I doubt it. So, without learning how to make some basic changes to scripts, looks like the only way you are gonna see their awesome artwork in a game is to add in the RP (or MM).
