Wow!!!!! You're a very good drawer! Better than me! You should be the drawer for this graphic novel! I'm sure everybody will agree! Particulary for the Andalites, they're so good!
Don't worry for KA, I think we don't need to ask her... Many people do doujinshi (it's a manga made by fans about other manga... there are many) and we won't gain money with it.
But of course, I'd be happy if Katherine come back on RAF *_*
