I'm not sure what is so great about the South Korean Box art, it looks like it was the rough draft for the Japanese box art. Alis looks like her head was cut and pasted, since it's not even in proportion, and Myau doesn't even look finished. The background completely lacks detail. I guess if you like the box cover to look like fan art.
The thing I found most funny about the scans is that I clicked the Japanese one, and Myau looks cute as can be, then I clicked the US one, and Myau looks vicious, almost like a monster, rather than a party member.
