Arakawa definitely went though a moon-faced period, and Roy still occasionally suffers from it, sadly ^^;. These are both from fairly recent issues. I like the character designs, like I said, but they don't hold up in every panel. The mouths that reach too far to the jaw is something else that she - unfortunately - tends to do, but it's the kind of thing that you can get away with more in a black-and-white manga. In animation, yeah, it just looks weird.
