Whether done as a cost-saving measure or to simply to provide fan service, all of the original Japanese voicework makes it over to the North American version. The appeal of such will obviously depend on how important it is for you to have the original voices. I'm squarely on the side that would prefer English voicework, but considering how shallow Atelier Annie's story is, it really didn't matter much to me. Still, I know there are purists out there who thrive on having the original voicework, so they should be happy. Music is appropriate to the series and the game's overall mood. It's peppy and upbeat, even at points where it doesn't need to be. Oddly enough, even in the game's darker moments (well, more like it's not-as-bright ones), the music works.
The bright tone carries through into the visuals. Characters have their own unique looks, all of which are typical of the series or JRPGs in general. Levels are composed mostly of small, one-screen rooms populated with a few set pieces for details and assorted characters, few of which have anything useful to say. A good deal of playtime is spent navigating menus, which should feel familiar to anyone who has played an Atelier game. If not, the tab system might feel a little clunky, but is readable.
