I was poking around on the Eternal Diva website (I don't know any Japanese so I was just randomly clicking links) and saw some pictures they called postcards. From the style of the art, I'd say they were from the ending credits of the movie.
Anyway, I decided to download them all and screencap them as well and share them with you guys, since I forgot where the link was.
SPOILERS
OBVIOUSLY
