This mod replaces all the paintings in the art gallery with Neptunia ones (even the ones not used by the game).
For a better experience and if you wish to use all the paintings available in the game, please download this mod.

Installation :

Simply un-zip and drag the Neptunia Art Gallery folder into your mod_overrides folder.
