There aren't as many publishers in Korea as there are in Japan, so we pretty much worked with all of them (until NetComics and IceKunion came along). It could be a house style (I don't know my Korean publishers as well as the Japanese, both because of the language barrier, and lack of time), but I don't think so. I tend to categorize the look as heavier inks, more static panel layouts (generally), fewer backgrounds but also less use of toned fills, eyes are dark and somewhat geometric, and limbs that are even more elongated than your typical manga. You get less of this in historical/shonen-type stuff, although there's still a bit of it there, and there are exceptions to the rule even within the shojo works, but it's pretty standard.

And in case it wasn't clear, for whatever reason, this is *not* a style that seems to resonate with most American readers. With few exceptions (Demon Diary being one), the Korean books sell horribly.
